硅胶表面螫合剂吸附重金属离子

Adsorption of Heavy Metal Ions by Silica Supported.

合成几种不同类型的硅胶表面螯合剂,研究它们对重金属离子的吸附能力。实验结果表明,四种吸附剂对四种不同的重金属离子均有一定的吸附能力,其中以吸附Cu^(2+)最大。此外,吸附还受溶液pH值影响,并对螯合剂进行洗脱研究。

Chelate reagents several silica supported chelate reagents havebeen synthesised and their adsorbabilities for metal ions studied. The resultsshow that the four samples have a definite adsorptivity for heavy metal ion,and they have a good adsorbtive power for Cu^(2+). Besides,the adsorptivity wasinflunced by pH.
