Abstract

Sonoelectrochemical degradation (US-EC), a relatively new AOPs, is a technique that combined sonication (US) and electrolysis (EC) without the need for additional chemicals for the procedure. Microcystin-LR (MC-LR), as the most toxic and most widespread algal toxin, are threat to human health. Until now US-EC technique have never been applied to MC-LR decomposition. The aim of this paper is to study the effect of MC-LR degradation of US-EC, optimize the sonochemical and electrochemical parameters involved in MC-LR decomposition. US-EC degradation of MC-LR was better than US or EC alone in terms of time and degradation efficiency. The degradation rate of MC-LR was up to 93% applying US (20 kHz ,15 W) to the EC (6 mA cm-2) for 5min, and the residual concentration of MC-LR in the water was less than 1µg L-1(the limits set by WHO). With processing time is extended to 10 minutes, the degradation rate was reached 99%.
