摘要
壳聚糖 (CS)溶液经戊二醛交联后 ,分子稳定性和抗降解性有较大提高。用交联壳聚糖 (CCS)与聚合氯化铝 (PAC)的复合试剂对水中染料进行脱色与除化学耗氧量 (COD)试验 ,结果表明 :CCS PAC复合试剂是一种用量少、脱色效率高、沉降速度快和稳定性好的复合高分子絮凝剂 。
Glutaraldehyde crosslinkage can improve considerably the molecular stability and anti degradation of the chitosan(CS) solution.The crosslinked chitosan(CCS) and polyaluminium chloride(PAC) together are proved effective to both the decolorization and COD tests of dyes in water solution.The experimental results show that CCS PAC compound is a complex polymer flocculation reagent with the small amount of usage,good stability,high decolorization,and quick subsidence,and offers a good prospect for further development and applications.
