Effects of Faujasite X and Y Zeolites on the 1,1,1-Trichloro-2,2? bis(p-chlorophenyl)ethane (DDT) Degradation during Water Purification
Kowenje, C. O.; Osewe, Elly T.; Lalah, J. O. (Science Publishing Group, 2013-06)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 ... -
Effects of Zeolite X on Dissipation of Hexazinone from Agricultural Waste Waters in Western Kenya
Agoro, D. J.; Kowenje, C. O.; Lalah, J. O.; Osewe, Elly T.; Ogunah, J. A. (2013-10)Dissipation of hexazinone in Zeolite X treated wastewater followed pseudo first-order kinetics giving a calculated half-life of 41 days compared to a half-life of 144 days in untreated wastewater. The herbicide degraded ... -
Effects of zeolites X and Y on the degradation of malathion in water
Ogunah, J. A.; Kowenje, C. O.; Osewe, Elly T.; Lalah, J. O.; Jaoko, D. A.; Koigi, R. N. (Science Publishing Group, 2013-04)The inclusion of both zeolites X and zeolite Y significantly affected the dissipation of malathion in water. In the fresh water, malathion degradation followed a pseudo-first order kinetics with concomitant half-life ...
