在盐酸介质中铑(Ⅲ)与二氯化锡反应生成红色络合物。首先提出作为分析使用,后又经一些作者补充改进成为一个较成熟的方法,但大多是测定低浓度范围。为了适应测定高含量的铑以及提高其测定的准确度,我们利用这个反应使用差示分光光度法进行了研究。差示分光光度法可测量高浓度同时准确度有时可与重量法相当。差示分光光度法的原理是作为空白溶液的不是单纯的试剂或水,而是使用比
Rhodium (III) reacts with tin dichloride in a hydrochloric acid medium to form a red complex. First proposed as an analytical use, and later by some authors to improve as a more mature method, but most of the determination of low concentration range. In order to adapt to the determination of high levels of rhodium and improve the accuracy of its determination, we used this reaction to study using differential spectrophotometry. Differential spectrophotometry can measure high concentrations with accuracy sometimes comparable to gravimetric methods. The principle of differential spectrophotometry is that instead of being a simple reagent or water as a blank solution,
