APPLICATION OF MODIFIED NANONATURALLY MONTMORILLONITE IN MONOCHLOROBENZENE REMEDIATION IN RIVER WATER.

As the inland waterway transportation developed rapidly in China, the frequency of hazardous chemical leakage accidents is increasing every year. Such pollution to inland river environment has become a world-wide issue. Montmorillonite (Mont) is typical 2:1 layer type silicate clay and due to their special structure, it has been used in organic pollution removal process. In order to improve their ability in pollution adsorption, the pillared Mont was made in this work. Since the common toxic structure in most chemical pollutants is the halogen atom-benzene ring part, we select a typical compound Monochlorobenzene (MCB) as the aim contaminant. In this research, the original Mont, -Mont, and -Mont were prepared and used in MCB degradation experiment as catalysts. The influence of catalyst amount, promoter () amount, MCB concentration and reaction time to MCB removal rate were studied, respectively in detail. [ABSTRACT FROM AUTHOR]
