现有的催化动力测定银的方法,灵敏度高达2×10~(12)g Ag.ml~(-1),其重要体系见表1。基于在过硫酸铵氧化锰(Ⅰ)时银起催化作用的原理,研究了测定痕量银的光度法。本法对常见元素的允许量较大。操作简单。
The existing method of catalytic kinetic determination of silver, the sensitivity of up to 2 × 10 ~ (12) g Ag.ml ~ (-1), the important system in Table 1. The photometric method for the determination of trace silver has been studied based on the principle that silver plays a catalytic role in ammonium persulfate (Ⅰ). The law allows for larger amounts of common elements. easy to use.
