本文用导数光谱法通过测定CrO_4~(2-)的含量,间接测定钼铁硫原子簇化合物中硫含量。用紫外一阶导数光谱来消除测定中干扰,免除了化学法消除干扰的麻烦。该方法测硫回收率为100±4％,精密度为4.0％。
In this paper, the content of CrO_4 ~ (2-) is determined by the derivative spectroscopy, and the sulfur content in the ferromolybdenum and sulfur cluster compounds is determined indirectly. Using UV first-order derivative spectra to eliminate interference in the assay eliminates the hassle of chemical methods of eliminating interference. The method of measuring sulfur recovery was 100 ± 4%, the precision of 4.0%.
