Abstract:
Pure cellulose was derived from cotton linter wastes followed by either acid hydrolysis or hypochlorite oxidation to obtain cellulosic samples having different molecular weights. The latter samples were cyanoethylated under identical conditions and used as dye adsorbent. It was found that the rate of dye adsorption depends on the concentration of the adsorbent, the nature of the charge on the dye used as well as the nature and magnitude of the charge on the adsorbent. the latter depends mainly on the nitrogen and carboxyl contents which depends mainly on the method of pretreatment which are highly affected by the method and conditions of pretreatment.
