摘要：Phenolic compounds are contained in effluents from various factories. Matsumoto reported the pollution of well waters by phenolic substances and proved the effluent source to be a coal gas plant. Underground permeation of phenolic substances from a dyestuffs factory into the wells beside the lower reaches of the Omuta river was also reported. Many substances such as medicines, nutritional substances and other natural biological substances contain compounds with phenolic groups, and the possibility of water pollution must be considered from effluents containing such substances. Water polluted by phenols shows high CODMn values. Therefore it is necessary to investigate the relationship between COD values and the chemical structure of phenolic compounds. A semimicro acidic or alkaline COD method was previously reported. In this report, the micro methods were adapted to determine the CODMn values of phenols.
