摘要：

Removal efficiency of monochloramine by rice bran was investigated over the range of pH 3-12. The removal rate of residual chlorine by rice bran was similar to activated carbon. Monochloramine was successfully removed with an average removal efficiency of 95% after 90 min when rice bran was applied to chlorinated sewage effluents that contained 0.22-0.46 mg/l monachloramine. The removal of monochloramine by rice bran was attributed to its decomposition by direct reaction with rice bran. Here, we report the findings of the efficiency of rice bran removal of monochloramine using the batch system in laboratory tests. and describe elucidation of the mechanism of its removal.
