The synthesis and characterization of zeolites designed for the removal of pesticide, radioactive waste and as slow release fertilizer is described. The zeolites were hydro thermally synthesized by varying the concentrations of Si and Al at different crystallization temperature between 75C to 150C. Different instrumental techniques viz. X-ray diffraction, FTIR, SEM, EDS, TEM and TGA were used to characterize the product obtained at different synthesis parameters. The broad and sharp peaks obtained in diffractogram shows the amorphous and crystalline nature of the materials respectively. The composition of SZM was found approximately close to the concentrations of the precursors taken during synthesis. The FTIR spectra of these zeolites in framework vibration region also shows sharp feature for zeolites in the 500-650cm-1. High crystalline nature of the material is reveals by the absorption bands at 520-570 cm--1 The synthesized zeolites were used for the sorption studies for malathion, Pd(II), Ru(III) and plant nutrient Nitrate.
