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 ... -
Predicting the thermal distribution in a convective wavy fin using a novel training physics-informed neural network method
Chandan, K.; Saadeh, Rania; Qazza, Ahmad; Karthik, K.; Kumar, R. S. Varun; Kumar, R. Naveen; Khan, Umair; Masmoudi, Atef; Abdou, M. Modather M.; Ojok, Walter; Kumar, Raman (Springer Nature, 2024-03-25)Fins are widely used in many industrial applications, including heat exchangers. They benefit from a relatively economical design cost, are lightweight, and are quite miniature. Thus, this study investigates the influence ... -
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 ... -
Spatial variation in physicochemical surface water quality in River Rwizi, Western Uganda
Ojok, Walter; Wasswa, John; Nakiguli, Caroline Kiwanuka; Ntambi, Emmanuel (Journal of Water Resource and Protection,, 2019)River Rwizi originates from the Buhweju hills. It is a major source of water for the inhabitants of Mbarara Municipality and surrounding environment. In this study, spatial variation of water quality in River Rwizi section ... -
Synthesis and characterization of hematite biocomposite using cassava starch template for aqueous phase removal of fluoride
Ojok, Walter; Ntambi, Emmanuel; Bolender, James; Wasswa, John; Wanasolo, William; Moodley, Brenda (Elsevier, 2022-08-24)In this study, facile synthesis of α-Fe2O3 biocomposite was mediated by cassava starch as a soft template. Batch mode evaluated its sorption behavior for fluoride removal from aqueous media. Characterization studies using ...
