| dc.description.abstract | The ability of zeolites to abstract and denature organochloride pesticides finds application in
water purification practices. In this study, activated faujasite X and Y zeolites were separately
exposed to 1, 2 and 4 ppm concentrations of 1, 1, 1-trichloro-2, 2'bis (p-chlorophenyl) ethane
(dichloro dipheny trichloroethane-DDT) water solutions. For the 1 ppm DDT solutions, the
resultant degradation products and residual DDT were minimal with concentrations in
zeolite treatments reducing to below detection limit (0.005 ppm) in about 2 hours. In addition,
the rate of dissipation was found to somewhat depend on the levels of DDT concentration
and the type of zeolite used. The main degradation product in samples exposed to faujasite
X was dichloro dipheny dichloroethylene (DDE) whereas in the faujasite Y exposed
samples, both the DDE and dichloro diphenyl dichloroethane (DDD) were obtained. | en_US |
