海绵镉的一般分析方法,最常用和最准确的,要算电解法。但是该法分离操作麻烦,并使用剧毒的氰化钾试剂,因此我们试验内电解分析方法,此法不但在操作上简单,迅速,而且也能得到与电解法同样的准确性。分析试样的成份内电解是一种不用外加电压而自发短路的电解,在一种溶液中采用不同的阳极金属,可以在白金阴极上析出不同的金属元素。因此对试料的杂质元素含量情况,需要进行系统的分析研究,掌握过去、现在和将来试料杂质变动情况,从此肯定操作程序。试验试样成份如表1 Sponge cadmium general analysis, the most common and most accurate, to be considered electrolysis. However, since this method is troublesome to separate and uses highly toxic potassium cyanide reagent, we test the internal electrolytic analysis method which is not only simple and rapid in operation but also achieves the same accuracy as the electrolytic method. Analysis of the composition of the sample Electrolytic electrolysis is a spontaneous short-circuit without the use of voltage electrolysis, in a solution using a different anode metal, platinum can be precipitated in the different cathode metal elements. Therefore, the content of the impurity elements of the sample need to be systematically analyzed and studied, to grasp the past, present and future changes in sample impurities, from affirmative operating procedures. Test sample composition shown in Table 1
