摘要: 将以氮为中心的交联淀粉与丙烯酰胺进行接枝共聚和磺化,合成了淀粉衍生物硫代氨基淀粉黄原酸盐(DSX),并通过红外光谱分析对其结构进行了表征。用DSX处理Cu2+,Pb2+,Zn2+,Cd2+浓度均为20 mg/L的模拟重金属废水,结果表明,当温度为20 ℃,pH为7,DSX投加量为1.5 g/L,处理时间20 min时,Cu2+,Pb2+,Zn2+, Cd2+的吸附去除率分别达到99.5%,99.4%,99.0%,99.2%。

Abstract: The starch derivatives DSX was synthesized by graft copolymerization and sulphonation of cross-linking starch and acrylamide with the center of Nitrogen.And its structure was analyzed by the Infrared spectra.An investigation on simulated heavy metal wastewater with 20 mg/L of Cu2+,Pb2+,Zn2+,Cd2+ was studied by using the starch derivatives DXS.It was showed that the average removal rates of Cu2+,Pb2+,Zn2+, Cd2+ were 99.5%,99.4%,99.0% and 99.2% respectively at temperature of 20 ℃, pH 7, DXS of 1.5 g/L for 20 minutes.

Key words: Starch derivatives DSX, Heavy metal wastewater, Removal
