水溶性甲壳胺制备及其对铅离子的螯合作用
PREPARATION OF WATER SOLUBLE CHITOSAN AND ITS CHELATION TO LEAD
【摘要】 报导了非均相体系制备水溶性甲壳胺(N,O—carboxymethylchitosan,NOCC)的实验条件。测定了各样品的取代度并分别研究了不同pH条件下NOCC的水溶解特性及其对铅离子的鳌合作用。
【Abstract】 The preparation method of water-soluble chitosan ( N, O-car-boxymethylchitosan, NOCC) in rionhomogeneous-phase system was reported. The degree of substitution were tested, the solubility and the chelating rate of NOCC to lead in different pH value water solution were studied respectively.
