Measurement of Total Organic Carbons in Inorganic Wastewater from Chemical Laboratories by Supercritical Water Oxidation Method

Abstract

Wastewaters containing more than several % of total organic carbons from chemical laboratories should be rejected in the process of wastewater treatment system composed of flocculation- sedimentation procedure in order to avoid technical troubles. Measurement system by supercritical water oxidation method was applied successfully to determine total organic carbons in chemical wastewaters containing various kinds of heavy-metallic compounds.
