| Abstract: | Cetylpyridinium bromide modified bentonite（CPB-Bt）,cetyltrimethyl ammonium bromide modified bentonite（CTMAB-Bt） and naphthalene ethylenediamonium chloride modified bentonite（NETH-Bt） were synthesized by modifying bentonite under microwave irradiation.The adsorption capacities of resultant organically modified bentonites for calcein in water were comparatively evaluated.It was found that calcein in water was eliminated at a rate of 98.58% under a calcein concentration of 25 mg·L-1,pH value of 2,adsorption time of 90 min,and CPB-Bt concentration of 10 g·L-1. |
