| Abstract: | Sonochemical degradation of p-chlorophenol
(CP) by coupling a well-known environmental friendly oxidant – iron (VI) in the form of potassium ferrate, with the assistance of sonication
(Sono ferrate) was experimented upon in this work. The efficiency of the method
was monitored by the degradation and mineralization of p-chlorophenol. The relevant parameters namely pH and ferrate: CP ratio were optimized. The optimal pH and the ferrate: CP ratio for the
sono ferrate method was found to be 8.0 and 3:1 at which the removal efficiency
with respect to chemical oxygen demand was found to be 85.7% in 75 min and the
mineralization efficiency (TOC removal) was 71.6%. It was observed that sono
ferrate method was more effective than simple ferrate method. Hence it is
recommended to use sono ferrate method as an effective, clean and green way of
degrading CP. |
