本文描述了金和银在聚氧肟酸螯合树脂上的吸附和解吸特性。在0.5M硝酸或中性溶液中定量地吸附金并用0.5％(重量/体积)氰化钾溶液迅速将金洗提下来。银自0.05M硝酸或中性溶液中除去,可被氰化物溶液或0.5M硝酸洗提下来。可从铜、铁和银中定量分离金;从氰化物稀溶液中吸附金和银。报道了用河水及其他洗提系统(湿法冶金和电镀溶液)的实验结果。
This article describes the adsorption and desorption properties of gold and silver on polyhydroxamic acid chelate resins. Gold was quantitatively adsorbed in 0.5 M nitric acid or neutral solution and gold was rapidly eluted with 0.5% (weight / volume) potassium cyanide solution. Silver is removed from 0.05M nitric acid or neutral solution and can be eluted with cyanide solution or 0.5M nitric acid. Gold can be quantitatively separated from copper, iron and silver; gold and silver are adsorbed from dilute cyanide solutions. Reported the experimental results of river water and other elution systems (hydrometallurgy and electroplating solution).
