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 Hexavalent Chromium Using Naturally Derived Flavonoids and Engineered Nanoparticles
Omowunmi, A. Sadik; Okello, Veronica; Osonga, Francis; Omole, Marcells A.; ’Owino, Isaac K (2014)Contaminated ground- and surface water supplies such as the municipalities, wells, lakes, and rivers exhibit various levels of contamination that can pose numerous health risks. The release of contaminants into the environment ... -
Kinetics of Degradation of Metribuzin in aqueous solution using Zero Valent Iron Nanoparticles
K’Owino, Isaac O.; Okello, Veronica; Masika, Kevin (2018-06)In this work, zero-valent iron nanoparticles (nZVI NPs) were synthesized in (EW-Fe0) ethanol -water mixed system and have been evaluated for degradation in aqueous solution of metribuzin. The batch experiments at varying ... -
Nanostructured Membranes for Water Purification
Omowunmi, A. Sadik; Du, Nian; Yazgan, Idris; Okello, Veronica (2014)Nanoscale materials can be used to achieve wastewater purification, desalination, and inactivation of pathogenic bacteria and viruses, as well as for the adsorption and/or degradation of contaminants [1 16]. The development ...
