摘要
本文利用XPS光电子能谱仪对D301树脂吸附金氰络合物前后的研究:确定此种吸附为离子吸附;D301树脂要达到较高的吸附量,必须先质子化;强的酸性环境可提高对Au(CN)_2^-的选择性,这一点在回收镀金废水中的金很有价值。
A study on the gold cyanide adsorption with D301 resin was made by using X-ray photoelectron spectrometry.It was affirmed to be the ionic type adsorption, In order to achieve a higher adsorptive capacity of D301 resin, its protonation is firstly essential. A strong acidic environment can significantly improve the selectivity of D301 resin adsorption of Au(CN)2-, which is important in the gold recovery from the waste water of gold plating.
