Abstract

In order to improve the adsorption performance of Attapulgite (ATP) on dyes. ATP was modified by cetyl trimethyl ammonium bromide (CTAB), and the ATP before and after modified were characterized with XRD and FT-IR. The results showed that ATP had been modified with CTAB successfully, and crystal structure of ATP was unchanged. The influence factors such as modified agent dosage, solution temperature, pH value of solution and dyes structure on adsorption properties of ATP were discussed. The results suggested that the optimal dosage of modifier was 10 wt% based on the quality of ATP. ATP had good adsorption effect on methyl orange when the pH value was pH value was in the rage of 3.6 to 11.6, temperature was in the range of 30- 50 oC. The order of adsorption effect was as follow: methyl orange>methylene blue>amido black>methyl blue>congo red>rhodamine B.
