METHOD OF DETERMINING EFFICIENCY OF PURIFYING WATER WHEN CLEANING WATER FROM ORGANIC POLLUTANTS WITH LIMITED VOLATILITY

摘要

FIELD: physics.;SUBSTANCE: efficiency of filters and devices for purifying household and industrial purpose water is evaluated. A composite index of the overall carbon content in organic compounds with limited volatility is used before and after purification. The overall carbon content is determined using gas chromatography with atomic-emission detection. Determination of the efficiency of purification using a highly sensitive method is invented. In that case the composite index of the overall carbon content correctly reflects the change in the quality of water during treatment.;EFFECT: high sensitivity of the method.;4 ex, 5 tbl
