摘要
针对国际回流法测定化学需氧量消耗时间长,试剂用量多,分析费用高等不足,研究了微波消解法快速测定高浓度水样的实验方法。通过微波消解功率、消解时间、催化剂用量、Cl-的干扰及消除等实验,确定了微波消解测定高浓度CODcr的最佳条件。
To make up the deficiency of international circumfluence method, such as high consumption of chemicals and reagents, high analysis cost, etc, a new method of microwave elimination was investigated, to speedily test the highly concentrated water sample. The best condition to measure the high concentrated CODer could determined by testing the methodical frequency, eliminating time, catalyst consumption, and the interference of Cl^-, during applying the method of microwave elimination.
