Removal Anionic Dye from Aqueous Solutions using Biopolymere
adsorption, metyl orange, chitosan
Abstract
Dyes have long been used in dyening, paper and pulp, texstile, plastics, leather paint, cosmetics and food industries. This poses certain hazards and environmental problems. the objective of this study is to investigate the adsorption behaviour of metyl orange from aqueous solution onto chitosan. The effect of initial dye concentration, contact time, initial pH, and adsorbent dosage were studied. the Langmuir and Fredlich adsorption models were applied to describe the equilibrium isotherm.
