Using the batch mode process, the effect of contact time, initial dye concentration (C), adsorbent dosage and pH was also investigated at room temperature of 25°C. It was observed that after 40 minutes equilibrium was attained and the percentage removal of dye decreased as initial pH was increased. Increasing the mass of the adsorbent resulted to an increase in the percentage of dye uptake (%R). The adsorption percentages were higher at lower initial concentrations of amaranth.  83.6% of dye was adsorbed at pH 2, adsorbent mass of 1.0 g and initial dye concentration of 30 mg/L. Langmuir and Freundlich isotherm models were used to explain the experimental data. Although equilibrium data were found to follow both isotherm models, the Freundlich model had the better correlation with the experimental data (R = 0.9894). Pseudo-first-order and pseudo-second-order kinetic models were used to analyze the adsorption kinetics. The pseudo-second-order kinetic model was found to agree well with the experimental data (R&#65533; 0.99). <#LINE#> @ @ Hameed B.H., Krishni R.R., Sata S.A., A novel agricultural waste adsorbent for the removal of cationic dye from aqueous solutions, J.

The pulping liquor was in the ratio of 1:6 based on bagasse.  The effect of pulping processes variables was investigated. Bagasse produced acceptable unbleached pulp at 80 C in plastic bag and at 105 C in autoclave, with different yield % from 43 % - 61%. The mechanical and physical properties of bagasse pulp sheet using different concentrations ratios of starch and/or borax as added filler during sheets making were investigated. The prepared sheets have been characterized by breaking length, tear index, burst index density and air permeability tests. Starch and/or borax filler added during sheet making improved the mechanical and physical properties of bagasse pulp sheet. <#LINE#> @ @ Navaee-Ardeh S., Mohammadi-Rovshandeh J., Pourjoozi   M., Influence of rice straw cooking conditions in the sodaethanol- water pulping on the mechanical properties of produced paper sheets, Bioresource Technology., 92, 65-69 (2004) @No $ @ @ Run Cang Sun Cereal Straw as a Resource for Sustainable Biomaterials and Biofue Chemistry, Extractives, Lignins, Hemicelluloses and Cellulose  Elsevier(2010) @No $ @ @ Charles M.,   Bagasse energy cogeneration potential in the Zimbabwean sugar industry, Renewable Energy, 28(2), 191-204 (2003) @No $ @ @ Hongjie Zhang, Jianguo Li, Huiren Hu, Zhibin He, Yonghao Ni, Improvement of bleached wheat straw pulp properties by using aspen high-yield pulp  Bioresource Technology 120 40–44 (2012) @No $ @ @ Biermann, Christopher J., Handbook of Pulping and Papermaking, 2nd Ed., 3 -Pulping Fundamentals, ACADEMIC PRESS,  55-110 (1996) @No $ @ @ El-Sakhawy M., Effect of bleaching sequence on paper ageing, Polymer Degradation and Stability,87(3), 419-423 (2005) @No $ @ @ Jahan M.S., Saeed A., Ni Y. and He Z., Pre-extraction and its impact on the alkaline pulping of bagasse,  Journal of Biobased Materials and Bioenergy,, 380–385 (2009) @No $ @ @ Sarwar Jahan  M., Shamsuzzaman  M., Mostafizur Rahman M., Iqbal Moeiz S.M., Ni Y., Effect of pre-extraction on soda-anthraquinone (AQ) pulping of rice straw   Industrial Crops and Products, 37, 164–169 (2012) @No $ @ @ Petroudy D., Rahman S. , Kristin S.,  Gary C.-Carrasco,  Ali G., Hossein R.,   Effects of bagasse microfibrillated cellulose and cationic polyacrylamide on key properties of bagasse paper, Carbohydrate Polymers, 99, 311-318 (2014) @No $ @ @ Ashori Alireza, Cordeiro, Nereida , Faria, Marisa, Hamzeh Yahya, Effect of chitosan and cationic starch on the surface chemistry properties of bagasse paper, International Journal of Biological Macromolecules,58,343-348 (2013) @No $ @ @ Nada A.M.A. El-Sakhawy M., Kamel, S.

PG College, Balrampur, UP, INDIA @ Department of Chemistry, Kisan PG College, Bahraich, UP, INDIA<#LINE#>26/12/2013<#LINE#>6/1/2014<#LINE#> Eight quantum chemical descriptors namely molecular weight, molar refractivity, HOMO energy, electronegativity, electron affinity, ionization potential, total energy and Log P of fifty four nitrobenzene derivatives have been calculated with the help of CAChe Pro of Fujitsu software using DFT methods and  the semiemperical PM3 methods. Observed toxicities of all compounds are in terms of -log (IGC50), mM, which is the inverse logarithm of the concentration causing 50% growth inhibition of Tetrahymena pyriformis after 40 hours. These eight descriptors have been used in the development of QSTR models. The QSTR model developed from descriptors molecular weight, molar refractivity, electron affinity and total energy have very high predictive power and can be used to find out the toxicity of any new derivative of nitrobenzene. Reliable QSTR models have been obtained from single descriptors namely electron affinity and total energy. The quality of regression has been adjudged by correlation coefficient, cross validation coefficient and statistical parameters like standard error, standard error of estimate, p-value, t-value, degrees of freedom etc. <#LINE#> @ @ Cronin M.T.D. and Schultz T.W., Development of Quantitative Structure-Activity Relationships for the Toxicity of Aromatic Compounds to Tetrahymena pyriformis: Comparative Assessment of the Methodologies, Chem.

The synthesized polymers were characterized using spectroscopic techniques like IR, UV and it confirmed the formation of the polymer. The thermal properties with their stability were studied using TGA, DTA and DTG and it was confirmed that the polymers were stable up to 700°C which is also evident from the activation analysis calculation. The X-ray analysis confirms the crystalline nature of the polymer which is also confirmed from the Scanning electron microscopic analysis.

In this study, attention has been paid to the synthesis, characterization and biological evaluation of new CoII and NiII complexes of CEFDX. The stoichiometrics and the mode of bonding of the complexes were deduced from their elemental and electrical conductivity measurements. For the characterization of the metal complexes various techniques like FTIR, UV-Vis Spectral study and TG-DSC were used. The composition of the complexes was identified as 1:1 ratio. Based on the study of infrared spectra, coordination through amide group and carboxylate group is proposed. Octahedral structures were proposed for these complexes depending upon the electronic spectral data. The thermal analysis data shows that water molecules have coordinate bonds with transition metal ion. Antimicrobial activity of thecomplexes was determined using Gram-positive strains of (Staphylococcus aureus) and Gram-negative strains of (Escherichia coli) bacteria by disc diffusion method.The antibacterial study of ligand and metal complexes were found to be better than the parent antibiotic. <#LINE#> @ @ Zayed M.A. and Abdallah S.M., SpectrochimicaActa Part , 60, 2215–2224 (2004) @No $ @ @ Shantier S.W., Gadkariem E.A., Ibrahim K.E. and El-Obeid H.A., E-Journal of Chemistry, 8(3), 1314-1322 (2011) @No $ @ @ Baertschi S.W., Dorman D.E., Occolowitz J.L., Spangle A.,  Collins M.W., Wildfeuer M.E. and Lorenz L.J., J.

The objective of adding color to foods is to make them appealing, augment the loss of color during processing, to improve the quality and also to influence the consumer to buy a product. At present, the demand for natural dyes is increasing worldwide due to the increased awareness on therapeutic and medicinal properties and their benefits among public and also because of the recognized profound toxicity of synthetic colors. Natural dyes are those derived from naturally occurring sources such as plants, insects, animals and minerals. Among all the natural dyes, plant-based pigments have medicinal values so are mostly preferred.  Today the food industry and color suppliers are however constantly motivated to work towards the improvement of the technical and physical properties of the color preparations. Development of cost-effective, viable technology for the preparation of a food color and its application in foods is a challenge and the need of the day. This review article covers recent developments in technological advances of food colors with respect to natural color application and stability in foods compared to synthetic colors and the detail basic chemical information about of the major pigments.  <#LINE#> @ @ Lawrence L.
