Synthesis and Adsorption Property of Polythioether Cellulose Compound
Abstract:
A kind of polythioether cellulose compound(PTEC) was synthesized by etherification of rice husk cellulose with chloromethylthiirane(CMT) in alkaline media. The preparation conditions have been investigated. The PTEC with 4.31% sulfur content was obtained by reacting 12 g rice husk cellulose with 36 mL chloromethylthiirane in 3 mol/L NaOH solution. The product has an adsorption capacity for Ag(Ⅰ) and Hg(Ⅱ) of 24.92 mg/g and 66.80 mg/g, respectively at pH=7 and for Pb(Ⅱ) it is 0.15 mg/g at pH=3. The fiber could be used as a adsorbent for metal ions.
