我厂冶金物料铅阳极泥、铜阳极泥、贵铅含银在5-50%之间,过去一直采用硫氰酸盐法或试金法测定.前者因试样中大量铜的存在往往需要复杂的分离手续,而试金法有耗电多、成本高、手续冗长和易引起铅中毒等缺点,为此我们选用原子吸收法. Our factory metallurgical materials lead anode mud, copper anode mud, expensive lead in silver between 5-50%, in the past has been measured by thiocyanate method or gold assay. The former due to the presence of a large number of samples of copper often requires complexity Of the separation procedures, and the test method has more power consumption, high cost, lengthy procedures and lead to lead poisoning and other shortcomings, for which we use atomic absorption method.
