研究出一种新的金提纯方法—碘法。它是用碘提纯金的闭路电化学方法。1)碘法包括再生循环系统,在隔膜电解槽(I_2—发生器)中制取化学剂(I_2,KOH);2)用碘
A new gold purification method was developed - iodine method. It is a closed circuit electrochemical method that uses iodine to purify gold. 1) The iodine method includes a regeneration circulation system for preparing chemicals (I_2, KOH) in a diaphragm cell (I_2-generator); 2)
