壳聚糖改性纸色谱法分离金属离子与氨基酸

Seperation of Metal Ions and Amino Acids by Chitosan-modified Paper Chromatography

采用壳聚糖改性层析纸 ,纸色谱法分离过渡金属、贵金属离子和氨基酸 ,与未改性层析纸进行对照。结果表明 ,壳聚糖改性纸色谱法分离效果及重现性较好 ,斑点集中、清晰 ,优于未改性层析纸。

A novel paper chromatography was developed to seperate metal ions and amino acids. The test paper was modified with chitosan solution to seperate the transition metal ions, noble metal ions and amino acids. In comparison with the unmodified paper, the modified paper is more efficient.
