Acid Dyes Removal Using Chitosan in Single and Binary Systems
Abstract:
It is now recognized that adsorption using low-cost adsorbents is an effective and economic method for water decontamination. Chitosan is derived by deacetylation of the naturally occurring biopolymer chitin which is the second most abundant polysaccharide in the world after cellulose. In this paper removal of two anionic dyes from textile effluent in both singular and binary systems is investigated. Direct Blue 78 and Acid Black 26 was used as anionic dye models. The surface characteristics of chitosan were investigated using Fourier transform infra-red spectroscopy and scanning electron microscopy. The influence of process variables such as adsorbent dosage and pH were studied. Results indicate that chitosan could be used as a biosorbent to remove the anionic dyes from contaminated watercourses in both singular and binary pollutants systems
