PSVA螯合树脂的合成及其对金属离子的螯合性能
摘要:
合成了大孔螯合树脂聚-N-亚水杨基乙烯基苯胺,研究了它对6种金属离子的螯合性能。结果表明,在pH=5时树脂对Cu2+的吸附容量达1.3mmol/g干树脂。据此提出了一个用此树脂回收废水中微量铜和除去光亮镀镍溶液中微量Cu2+的方法,效果良好。

SYNTHESIS AND CHELATING PROPERTY OF MACROPOROUS RESIN PSVA
Abstract:
In this paper the synthesis and chelating property of a macroporous chelate resin,poly-N-salicylidene vinylaniline (PSVA) are studied. It is found that the resin has a good adsorbability for Cu2+ at pH=5 and for Fe3+ in 0.17 mol/L HCl. The adsorption capacity was 1.35 mmol Cu2+ per g PSVA. A satisfactory result was obtained, using PSVA resin in removing trace amount of Cu2+ from nickel electroplating solution and wasted water. The resin can be regenerated by successively washing with mixture of 5%EDTA and 1.5mol/L H2SO4.
