Enhancement of Chloramphenicol Sonochemical Degradation by Sodium Peroxydisulfate

Article Preview

Abstract:

Sonochemical degradation of the antibiotics chloramphenicol in aqueous solution with sodium peroxydisulfate sulphate (SPDS) enhancement was investigated. The preliminary studies of optimal degradation methodology were conducted with sole SPDS, cobalt activated SPDS (SPDS/Co2+), ultrasonication with SPDS (SPDS/US) and ultrasonication with cobalt activated SPDS (SPDS/Co2+/US). The effect of the initial pH values of the aqueous solution on the sonochemical degradation rate of chloramphenicol was also investigated. The results showed that the sonolysis of chloramphenicol can be accelerated remarkably by adding SPDS and the efficient treatment method for treating the chloramphenicol wastewater was ultrasound coupled cobalt activated SPDS. The ultrasonic degradation rate constants in acidic water are higher than those obtained in neutral or basic aqueous solutions.
