ADSORPTION OF ANIONIC DYES BY STARCH NANOCRYSTALS GRAFTED POLYETHYLENEIMINE

  • 摘要: 以戊二醛为交联剂、淀粉纳米晶(SNCs)为基材接枝聚乙烯亚胺(PEI),成功制备了一种新型生物基吸附剂(SNCs-PEI)。利用粒径、Zeta电位、红外光谱(FTIR)和能量色散X射线谱(EDX)对SNCs-PEI进行表征,并探究其对阴离子染料的吸附效果。当pH=3时,SNCs-PEI 的Zeta电位达到+37.9 mV,对阴离子染料甲基橙(MO)和刚果红(CR)均具有良好的吸附性能,考察了吸附时间、pH值、染料初始浓度、温度对SNCs-PEI吸附性能的影响。研究表明:在pH为3,SNCs-PEI投加量为0.1 g,MO、CR初始浓度为130 mg/L的条件下,SNCs-PEI对MO和CR的吸附过程均符合准二级动力学和Langmuir吸附模型,SNCs-PEI对MO、CR的最大吸附量分别为82.10,57.34 mg/g,吸附过程属于一个自发的吸热过程。该新型生物吸附剂的研究对含阴离子染料工业废水的去除提供了一种新途径。
