摘要：
The chemical oxygen demand (COD) test is widely used by industry, commercial laboratories, and municipal wastewater treatment authorities. The use of silver (Ag) as a catalyst and of mercury (Hg) to reduce interferences is important to the precision and accuracy of the results, but these chemicals add to the cost of the test, and their disposal may cause environmental problems. This paper describes a treatment method for COD test waste that effectively removes silver and mercury separately without requiring pH adjustment or generating toxic gases.
