用分光光度法测定了焦化脱硫液中硫氰酸铵的含量。通过实验确定反应溶液在460mn有最大吸收。利用分光光度法在该波长下进行比色测定，含量在（O～300）g／L范围内符合比尔定律，其线性回归方程为C=476．19A＋0．02（R^2=0．9998）。该方法测定脱硫液中硫氰酸铵含量快速、准确、重现性好、试样无需特殊处理。

In lab ammonium rhodanide in desulfurized liquor was measured by means of spectrophotometr. The substance had maximum absorption at 460nm. When ammonium rhodanide was in the range of (0 - 300) g/L, it was in accord with Beerg law, its linear regression equation was C = 476.19A + 0.02 (R = 0.9998). Rapid, accurate measurement and good repeatability for ammonium rhodanide in desulfurized liquor could be realized by means of the method, no special treatment for sample was made.
