研究了从含金水溶液中分离和回收金的方法,结果表明:在2molHCl介质然后用聚氨酯泡沫塑料柱层法吸附的金,能够用pH=4～5的盐酸水溶液解吸,中,用过氧化氢或硫酸亚铁溶液沉积解吸液中的金.
The method of separating and recovering gold from gold-bearing aqueous solution was studied. The results showed that the gold adsorbed in 2mol HCl media and then packed in polyurethane foam column can be desorbed by hydrochloric acid solution with pH = 4 ~ 5. Hydrogen peroxide Or ferrous sulfate solution to deposit gold in the desorption solution.
