摘要
在30℃、pH2条件下研究了精金矿中7种杂质金属离子铁、钙、钢,锌,铝、镁和铅对活性炭从硫(?)溶液吸附金时在吸附等温线和吸附速度方面的影响。文中比较了各种离子对吸附影响的大小,提出了影响原因,并以实验结果证实了上述离子基本不被吸附。
The effect of seven metallic ion impurities (Fe, Ca, Cu, Zn, Al, Mg and Pb)was experimentally investigated on the adsorption rate and isotherms of gold from a thiourea solution at 30℃ and pH2. The different effects of all these ions on the adsorption were compared with one another, and the associated mechanism were clarified. It was confirmed that the above mentioned ions are hardly absorbed.
