Assessment of contamination level of a Tanzanian river system with respect to trace metallic elements and their fate in the environment
Gebreyohannes, Netsanet; Rwiza, Mwemezi; Mahene, Wilson (IWA Publishing, 2022-04-01)The quality of water and sediments from a marginally-studied river was investigated with respect to As, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn including their fractionation behavior and environmental risk. Samples were collected ... -
Cockle (Anadara granosa) shells-based hydroxyapatite and its potential for defluoridation of drinking water
Mtavangu, Stanslaus; Mahene, Wilson; Machunda, Revocatus; Bruggen, Bart; Njau, Karoli (Elsevier, 2022-03-03)The present study describes the synthesis and characterization of a hydroxyapatite (HAp)-based adsorbent derived from biogenic cockle (Anadara granosa) shells for the defluoridation of drinking water. The raw cockle shells ... -

In-situ synthesis of calcium/magnesium phosphate system for water de-fluoridation: Clay ceramic materials
Mahene, Wilson; Hilonga, Askwar; Machunda, Revocatus (Elsevier, 2022-02-15)Clay ceramic water filters impregnated with silver colloids have been used to purify water in many parts of East Africa disregarding the removal of fluoride, which is a health-threatening ion in water supplies. This paper ... -
The role of textural properties and surface chemistry of activated carbon support in catalytic deoxygenation of triglycerides into renewable diesel
Mahene, Wilson; Kivevele, Thomas; Machunda, Revocatus (Elseiver, 2023-07)The textural properties and surface chemistry of activated carbon support are commonly known to have influ- ence on the catalytic performance of catalysts. Many authors have assessed the effect of textural properties ... -
Synthesis and FTIR Characterization of Mg-Hydroxylapatite Derived from Dolostone with High Dolomite Mineral Content
Mahene, Wilson; Gervas, Charles; Hilonga, Askwar; Machunda, Revocatus (University of Dar es Salaam, 2020-08-24)We present the synthesis of magnesium-substituted hydroxylapatite starting from locally available dolostone. The apatite was prepared by a reaction between heat pre-treated dolostone powder with phosphoric acid, maintained ...
