The intermixture of positive ion surfactant Cetyltrimethyl Ammonium Bromide and zwitterion surfactant N

N-C_{12}BE was used to modify the natural zeolite. Correlative parameters of modified zeolite adsorbing Cr(Ⅵ) and phenol from wastewater were studied. The results indicate that when the pH is 6

8

the stirring rate is 160 r/min

the modification concentration is 2.0% and the adsorption time is 30 min

the rate of removing is more than 90%

which offers a new kind of environmental protection material for treating wastewater

open up a new way for empoldering and applying nature zeolite.
