硅藻土及其复合物处理有机污染物的研究进展

Research progress on treatment of organic pollutants by diatomite and its complexes

综述了改性硅藻土在吸附催化处理有机污染物方面的进展和研究成果。文献研究表明,硅藻土在经过有效改性后可大大提高孔径、孔隙和比表面积,增加吸附位点,从而大大提高硅藻土对有机污染物的吸附催化效率。改性硅藻土对很多有机污染物(例如亚甲基蓝、刚果红、苯酚、甲醛等)都有良好的吸附或降解效果,且部分研究成果已经实现产业化,在日常生产生活中起到重要作用。

The progress and research results of modified diatomite in the adsorption and catalytic treatment of organic pollutants were reviewed.Literature studies shown that diatomite can greatly increase its pore size and specific surface area after effective modification,and increase its adsorption sites,thereby greatly improving the catalytic efficiency of diatomite for organic pollutants adsorption.Modified diatomaceous earth has a good adsorption or degradation effect on many organic pollutants(such as methylene blue,Congo red,phenol,formaldehyde,etc.),and some research results have been industrialized,playing an important role in daily production and life.
