The Dissipation of Carbofuran in Two Soils with Different Pesticide Application Histories within Nzoia River Drainage Basin, Kenya
Kimosop, Selly Jemutai; Orata, Francis O.; K’Owino, Isaac O; Getenga, Zachary M. (Bulletin of Environmental Contamination and Toxicology, 2014-02-28)The dissipation of carbofuran from soils within the Nzoia River Drainage Basin in Kenya was studied under real field conditions for 112 days. Results showed significantly enhanced dissipation of carbofuran with half life ... -
Green Remediation of Carbamazepine from Water Using Novel Magnetic Iron Modified Carbonized Baggasse: Kinetics, Equilibrium and Mechanistic Studies
Kimosop, Selly Jemutai-; Okello, Veronica A.; Orata, Francis; Getenga, Zachary M.; Shikuku, Victor O. (Chemical Science International Journal, 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 has ... -
Insights on adsorption of carbamazepine onto iron oxide modified diatomaceous earth: Kinetics, isotherms, thermodynamics, and mechanisms
Kimosop, SellyJemutai; Orata, Francis; Shikukub, Victor O.; Okelloc, Veronica A.; Getenga, Zachary M. (Environmental Research, 2020-01)To ameliorate adsorbent recovery by an external magnetic field, naturally occurring diatomaceous earth (DE) was modified with iron-oxide, characterized and applied for adsorption of carbamazepine (CBZ) from synthetic ... -
Synthesis of mesoporous akaganeite functionalized maize cob biochar for adsorptive abatement of carbamazepine: Kinetics, isotherms, and thermodynamics
Kimosop, SellyJemutai-; Okello, Veronica A.; Shikuku, Victor O.; Orata, Francis; Getenga, Zachary M. (Cleaner Materials journal homepage: www.journals.elsevier.com/cleaner-materials https://doi.org/10.1016/j.clema.2022.100104 Received 16 March 2022; Received in revised form 6 June 2022; Accepted 12 June 2022, 2022-06-17)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. ... -
