Characteristics of pentachlorophenate degradation in aqueous solution by means of ultrasound

Article Abstract:

The results of the ultrasonic degradation of pentachlorophenate in an aqueous solution are dependent on the type of gas that saturates the solution. Pentachlorophenate, an aromatic halide, was exposed to 530 kilohertz of sonochemical degradation. In a saturated argon solution, carbon monoxide was produced during degradation. In an saturated oxygen or air solution, pentachlorophenate is mineralized to carbon dioxide. Further analysis of the sonochemical degradation of pentachlorophenate is presented.

Modeling of sonochemical decomposition of CCl4 in aqueous solutions

Article Abstract:

An investigation into the feasibility of using sonolysis of carbon tetracholoride in aqueous system to remove organic pollutants in the aqueous system is presented. The system is based on the ability of the sonolytic process to produce conditions of high temperature and pressure in the expansion and collapse of the vapor formed by the ultrasound. Each cavitation yields intermediates which are then degraded in subsequent cavitations.

Effects of chlorophenols and nitrophenols on the kinetics of propionate degradation in sulfate-reducing anaerobic systems

Article Abstract:

Chlorophenols and nitrophenols had varying toxic effects on acetate utilization and propionate degradation in a sulfate-reducing anaerobic system. The impact of chlorophenols was much higher in propionate degradation reactions than in acetate utilization reactions. However, the impact of nitrophenols is the reverse of chlorophenols with respect to reactions involving acetate utilization and propionate degradation.
