Facile synthesis and characterization of multi-walled carbon nanotubes decorated with hydroxyapatite from cattle horns for adsorptive removal of fluoride.
Ojok, Walter; Bolender, James P.; Wasswa, John; Ntambi, Emmanuel; Wanasolo, William; Moodley, Brenda (Elsevier Ltd., 2023-03-09)Developing a new adsorbent for fluoride removal from cattle horn waste materials by a facile chemical method has shown great potential for fluoride removal. This paper reports the synthesis of multi-walled carbon nanotubes ... -
Hydrochemistry and fluoride contamination in Ndali-Kasenda crater lakes, Albertine Graben: assessment based on multivariate statistical approach and human health risk.
Ojok, Walter; Wanasolo, William; Wasswa, John; Bolender, James; Ntambi, Emmanuel (Elsevier, 2021-08-08)Hydrochemistry of crater lakes (n = 15) in the Ndali-Kasenda cluster was deciphered using standard methods of the American Public Health Association to understand the major ion chemistry; spatial distribution, occurrence, ... -
Mobility of chromium, copper and arsenic in amended chromated copper arsenate contaminated soils
Nakiguli, Caroline Kiwanuka; Ojok, Walter; Omara, Timothy; Wasswa, John; Ntambi, Emmanuel (Asian Journal of Applied Chemistry Research, 2020-09-23)The use of copper-based preservatives such as chromated copper arsenate (CCA) and creosote to prolong the life of lumber present environmental concerns because they contain heavy metals and polycyclic aromatic hydrocarbons ... -
Role of starch in one pot fabrication of mesoporous gamma-alumina with excellent fluoride sorption capacity
Ojok, Walter; Moodley, Brenda; Wasswa, John; Ntambi, Emmanuel; Wanasolo, William; Bolender, James (Elsevier Ltd., 2023-08-28)Green synthesis of mesoporous γ-AƖ2O3, a cutting-edge material for sustainable application in medicine, engineering, energy, and water treatment, is still challenging. Our study used a one-pot strategy for facile synthesis ... -
