Abstract:
This study focused on enhancing photocatalytic degradation of microcystin-LR following the addition of ferrate to the process. The degradation efficiency of ferrate and the photocatalysis was 54% and 63% respectively. However, when ferric or ferrate was added to the photocatalytic process, a significant enhancement in the rate of the photocatalytic degradation was observed and the efficiency can be increased to 73% or 100%. The results demonstrate that relatively low ferrate doses (10 mg/L) are sufficient not only for pre-degradating amount of toxin but also for supplying the Fe3+ enhance the rates of photocatalytic process to destroy the toxin further. At the same time, it indicates the advantage of using ferrate with the photocatalytic system comparing with ferric.
