Preparation of Cellulosic Adsorbent for Heavy Metal Ions with Microwave Irradiation
A new kind of cellulosic adsorbent for heavy metal ions was prepared by grafting copolymerization in microwave irradiation field, where acrylic acid (AA) and acrylamide (AM) were used as monomers and carboxymethyl cellulose (CMC) was used as bond. The effects of factors such as microwave irradiation power and time, dosage of initiator (sodium persulfate) and crosslinker (N, N’-methylene bisacrylamide), and neutralization degree on the adsorption for Cu2+ were investigated. Experimental results showed that the optimal conditions were as follows: microwave irradiation power and time was 360 W and 3.5 min, respectively; dosage of initiator and crosslinker was 4.1 g/L and 1.9 g/L, respectively, and neutralization degree was 75%.
