Abstract

In this article, adsorption process has been found to be one of the best treatment methods for Methylene blue (MB) removals. As the control of water pollution has become an increasing importance in recent years, the use of physical/chemical treatments such as membrane filtration, reverse osmosis, coagulation/flocculation and fenton reagents are not economically feasible. The use of different biosorbent as an alternative low cost adsorbent in the removal of methylene blue has been extensively studied and compiled, together with their adsorption capacities and experimental conditions such as adsorbent dose, pH of the solution, temperature and equilibrium time. But, there are issues as regards to draw back in the use of activated sorbents which were also discussed briefly. However, it is evident from the results of experiments in the literatures surveyed that various low-cost adsorbents have shown good potential for MB.
