摘要
对比了6种酸体系对二苯碳酰二肼光度法测量六价铬的影响,得出盐酸体系步骤简化,分析速度快,易操作。线性关系、精密度、准确度能得到保证。
The impacts with six kinds of acid system on diphenylcarbohydrazide spectrophotometric method used to determine hexavalent chromium in the water are compared. The results indicate that hydrochloric acid system is simple to operate with rapid speed, which can guarantee the high precision and accuracy.
