壳聚糖膜用于去除六价铬。调查涵盖相转化（湿法）生产的膜。膜的改性是通过乙酰化和交联的Cu（II）。在实验中，使用了波兰海洋渔业研究所生产的壳聚糖。在膜过程中，金属离子在壳聚糖膜上被去除。考察了改性前后膜的分离性能以及溶液pH值对膜分离性能的影响。采用电感耦合等离子体（ICP）原子发射光谱法测定金属离子的浓度。
Chitosan membranes were used for hexavalent chromium removal. Investigations covered membranes produced by phase inversion (wet-method). The modifications of membranes were made by acetylated and cross-linked Cu(II). In the experiments chitosan produced by the Sea Fisheries Institute, Poland, was used. The metal ions were removed on chitosan membranes during membrane processes. The modifications and the effect of the pH of the solution on the separation properties of membranes were determined. The concentration of metal ions was measured by the method of inductively coupled plasma (ICP) atomic emission spectrometry.
