Abstrakt: | A mathematical model of acid-basic CO2 equilibrium in a gas - liquid system was worked out, enabling to determine quantity of produced CO2 through chromatographic analysis of gaseous phase. Under appropriate test conditions, biodegradability of model samples was explored. Course of biodegradation was studied through produced CO2 determined by analyzing gaseous phase through GC on the one hand, and through customary "titration" procedure on the other. The procedures in question are "substituting" procedures for observing course of aerobic biodegradation of substances in an aqueous environment. | ||||||||||
