متن کاملAdsorption of Remazol Black B Dye from Aqueous Solution Using Bagasse
The dye of wastewater is a major environmental problem. Chemical and biological treatment of wastewaters containing dye is difficult due to the low level of adsorption and chemical stability of dyes. Activated carbon is usually used for adsorption of these materials, but because of high prices and restore problems, researchers trying to find available, low-cost materials with high adsorption. I...
متن کاملRemoval of Congo red from aqueous solutions using nano-Chitosan
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 study, the capacity of the chitosan nanoparticles was studied for the removal of the anionic Congo red...
