| Abstract: | A pilot experiment for gold recovery from the gold-electroplating wastewater was conducted and the influence of various process conditions was studied. The experimental result showed that under optimum operation conditions, 99. 9% pure gold could be recovered by batch process of one stage liquid membrane seperation and the recovery rate was 99. 1%. This method has some advantages,such as short scheme,quick speed and high effciency,and pontential industrial application. |
