Igboamalu, Tony Ebuka; Nyakale, Atlegang; Matsena, Mpumelelo Thomas; Chirwa, Evans M.N. (Italian Association of Chemical Engineering, 2020)Biocatalytic oxidation of Arsenite (As3+) to arsenate (As5+) in a mobilized and immobilized chemoautotrophic bacterium has been a challenging area of metallic bioremediation research. This is because arsenic in its trivalent ...

Igboamalu, Tony Ebuka; Needham-Clark, Benjamin; Matsena, Mpumelelo Thomas; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019)The energy output of a dual chamber anoxic microbial fuel cell (MFC) subjected to variation in the substrate concentration was investigated. Wastewater from a primary clarifier effluent stream was used as the MFC inoculum. ...

Kholisa, Buyisile; Matsena, Mpumelelo Thomas; Chirwa, Evans M.N. (Wiley, 2023-06)Chromium (Cr) has been extensively used in many industrial applications. Inappropriate disposal of effluent has led to increased Cr concentrations in the environment. As a result, Cr(VI) has been classified under strict ...

Igboamalu, Tony Ebuka; Bezuidenhout, Neil; Matsena, Mpumelelo Thomas; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019)The primary objective of all microbial fuel cell (MFC) research is currently to find ways to increase its efficiency by optimising design architecture and operating values. Microbial fuel cells (MFCs) are however very ...

Matsena, Mpumelelo Thomas; Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)Hexavalent chromium [Cr(VI)] which are discharged together with organic pollutants in effluent streams from industry pose a health hazard to humans. The present study observed the reduction of Cr(VI) in presence of phenol ...

Matsena, Mpumelelo Thomas; Tichapondwa, Shepherd Masimba; Chirwa, Evans M.N. (MDPI, 2020-08)Palladium (Pd) is a cheap and effective electrocatalyst that is capable of replacing platinum (Pt) in various applications. However, the problem in using chemically synthesized Pd nanoparticles (PdNPs) is that they are ...
