Study on decoloring capability of pyridine modified bentonite to direct fast turquoise blue dye wastewater
吡啶改性膨润土对直接耐晒翠蓝染料废水脱色性能研究

To solve the increasingly serious water pollution problems,a new type of water treatment agent was prepared,which took pyridine as modifier,made organic modification to bentonite,and was applied to the direct fast turquoise blue dye wastewater treatment.The optimum conditions for wastewater treatment were studied.The results showed that by using modified soil,when investment soil volume was 10 g/L,pH was 3.5,stirring intensity was 175 r/ min,stirring time was 25 min,centrifugal time was 2 min,the decoloriza...
