Synthesis of Double Crosslinked Amphoteric Cassava Starch Resin and Performance of Absorbing Cu (II)

Abstract:

Sodium polyphosphate-crosslinked starch was synthesized by using cassava starch and sodium polyphosphate as main material and crosslinked agent individually. On above basis, double crosslinked amphoteric cassava starch resin was synthesized by N,N'-methylene bisacrylamide as inner-crosslinked agent, dimethyl diallyl ammonium chloride (DMDAAC) and acrylic acid as amphoteric grafted monomer. The product was characterized by infrared spectrum (FTIR). The results indicate that the cassava starch was modified successfully, and the final product was double crosslinked amphoteric cassava starch resin. Adsorption behavior of Cu²⁺was studied in the condition of different adsorption time, and found that the removal rate and the adsorption capacity of Cu²⁺ reached up to 98.3% and 196.6 mg/g respectively.
