Preparation, Characterisation of Chitosan Modified Bentonite and Application to Methylene Blue Adsorption

Abstract:

Article Preview

A effective and cheap adsorbent, chitosan modified bentonite was prepared in this work. XRD, SEM and FTIR were used to characterize unmodified and chitosan modified bentonite materials. The adsorption property of bentonite and modified bentonite for mythlene blue in wastewater were investigated by spectrophotometry. The effects of initial pH value, sorbent dosage and contact time on the adsorption capacity have been investigated. The chitoan modified bentonite showed excellent removal capacities for methylene blue from waste water.
