The removal effect of nitrobenzene in the aqueous solution is studied by using the oganic bentonite modified by CTMAB.The results show that the best removal efficiency of nitrobenzene was up to 62.4%,while the modified organic bentonite addtion amount was 1g/50ml of 10mg/L nitrobenzene solution,the adsorption was balanced when the adsorption time was 80 min and initial concetration of wastewater was 10mg/L,PH value little affects...
