壳聚糖吸附水溶液中微量Pb2+的研究
Study on the Sorption of Pb2+ in Water by Chitosan
摘要
Abstract
The trace amount of Pb2+In water can be removed by using chitosan as adsorbent.The sorption property of chitosan to Pb2+ ion was investigated.The influence of the amount of chitosan and its particle size,the pH value in solution and sorption time on the sorption of Pb2+ to chitosan was discussed.It is found that chitosan is a good adsorbent for Pb2+ in water solution.More than 99.7% Pb2+ in water solution can be removed by chitosan.The sorption optimum of chitosan consumption:100mg;grain diameter: 0.3～0.8mm;pH:6～8;time:5～8h.Eliminated rate of Pb2＋ was more than 99.7% and remains concentration of Pb2+ in water (≤0.6mg/l) had reached china nation standard about waste water drainagn.Analysis for infrared and ultraviolet spectra showed that the sorption could take place between—NH2,—OH,C—O—C in Chitosan and Pb2+ efficiently.关键词
