| Abstract: | Organomontmorillonite(CMt) prepared by ion exchange method was used as carrier and dispering agent for synthesizing Nanoscale zero-valent iron(NZVI),by adopting aqueous reducing technique.The NZVI(NZVI-CMt) was characterized by XRD and SEM.The removal rate of 4-chlorophenol by NZVI-CMt was investigated under different conditions.In addition,the degradation mechanism of 4-chlorophenol was discussed.The experimental results demonstrated that the supported NZVI was well-dispersed,with a particle size range of ... |
