ABSTRACT

In this paper, a new adsorption material was prepared by using the chemical-modified natural cellulose, namely TEMPO-oxidized natural cellulose. And ferric ion-sorption experiments were also carried out in order to study the adsorption properties of the new materials. Natural cellulose has great superiority as the new experimental material, since cellulose is the most abundant and renewable biopolymer and is one of the promising raw materials available in terms of cost for preparing various functional materials. And so, it will provide strong support for the application of this new type of adsorbent. With the single variable controlling method, all kinds of factors affecting the adsorption efficiency were investigated, and the optimum conditions for the new removal of iron ions with TEMPO-oxidized natural cellulose were determined.
