Biodegradation of carbofuran in soils within Nzoia River Basin, Kenya
Onunga, Daniel O.; Kowino, Isaac O.; Ngigi, Anastasiah N.; Osogo, Aggrey; Orata, Francis; Getenga, Zachary; Were, Hassan (Taylor & Francis, 2015)Carbofuran (2,3-dihydro-2,2-dimethylbenzofuran-7-yl methylcarbamate) has been used within the Nzoia River Basin (NRB), especially in Bunyala Rice Irrigation Schemes, in Kenya for the control of pests. In this study, the ... -
Comparative studies in electrochemical degradation of sulfamethoxazole and diclofenac in water by using various electrodes and phosphate and sulfate supporting electrolytes
Sifuna, Fred W.; Orata, Francis; Okello, Veronica; Kimosop, Selly J. (Taylor and Francis, 2016-06)In this study, the electro-oxidation capacities of Na2SO4 and potassium phosphate buffer supporting electrolytes were tested and compared for destruction of the sulfamethoxazole (SMX) and diclofenac (DCF) on platinum (Pt) ... -
Green Remediation of Carbamazepine from Water Using Novel Magnetic Iron Modified Carbonized Baggasse: Kinetics, Equilibrium and Mechanistic Studies
Okello, Veronica A.; Kimosop, Selly J.; Getenga, Zakari M.; Orata, Francis; Shikuku, Victor O. (SCIENCE DOMAIN, 2017-03-15)Baggasse derived biochar magnetically modified with iron (α-Fe2O3-CBG) was fabricated, characterized and applied as a low-cost adsorbent for the removal of carbamazepine (CBZ), a pharmaceutically active compound which ... -
The Influence of Filter Mud Compost and Tithonia diversifolia Leaves on the Dissipation of Diuron in Soils within the Nzoia River Drainage Basin, Kenya
Kimosop, Selly Jemutai; Orata, Francis; Getenga, Zachary (Springer, 2012-05-22)The aim of the study was to evaluate the environmental impact of filter mud compost and Tithonia diversifoila amendments on the dissipation of diuron in sugarcane cultivated soils. Filter mud compost is the by-product of ... -
Synthesis of mesoporous akaganeite functionalized maize cob biochar for adsorptive abatement of carbamazepine: Kinetics, isotherms, and thermodynamics
Selly, Jemutai Kimosop; Okello, Veronica A.; Shikuku, Victor O.; Orata, Francis; Getenga, Zachary M. (Elsevier, 2022-09-01)In this work, akaganeite (β-FeO(OH)) impregnated maize cob biochar (Fe-MCB) was prepared by direct hydrolysis, and its adsorptive potential was tested against aqueous solutions of carbamazepine (CBZ), an emerging contaminant. ...
