(University of Pretoria, 2017)The development of pyrethroid resistance in mosquitoes threatens the goal of malaria elimination in Africa. Alternative insecticides, e.g. organophosphates, can be considered to control pyrethroid resistant mosquitoes. The ...
-
(Wiley, 2022-08)The effect of various clays nanofillers on the photo-oxidation of polyamide 11 (PA11) has been investigated by accelerated ultraviolet (UV) test up to 780 h. Organo-modified montmorillonite, halloysite nanotubes, and ...
-
(SpringerOpen Journal, 2015-12)BACKGROUND : South Africa uses indoor residual spraying (IRS) for vector control in its malaria control programme (MCP). Insecticide-treated wall linings (ITWLs) offer possible advantages over IRS and long-lasting, ...
-
(University of Pretoria, 2010-08-19)The SAPPI Ngodwana mill is the largest integrated pulp and paper mill in Africa and is situated in the Elands River catchment in the Mpumalanga province. A need has arisen at the mill to reduce effluent volumes requiring ...
-
(University of Pretoria, 2020)A mathematical model of a continuous Kraft wood digester was developed and tested. The model relies heavily on the work done previously by Christensen, Albright & Williams (1982). The batch Kraft digester model developed ...
-
(Elsevier, 2020-03)The nature of the interaction of low molecular weight natural organic matter (NOM) with the Ag (1 1 1) surface is of crucial importance in the environment. The low molecular weight organics used in this study are formic ...
-
(Italian Association of Chemical Engineering, 2022)Arsenic (As) contamination is a major concern due to its toxicity and tendency to accumulate and bio-magnify within the food chain, causing wider damage to the ecosystem. In the current study, activated carbon-supported ...
-
(The Italian Association of Chemical Engineering, 2019)Attapulgite clay also known as palygorskite is a mineral clay which possess good adsorption properties based on its adsorption capacity, porous structure and moderate cation exchange properties. The study investigated the ...
-
(Italian Association of Chemical Engineering, 2023)In this study, microcrystalline cellulose (MCC) was utilised as an adsorbent for the removal of Cr(VI) from synthetic wastewater. FTIR spectroscopy confirmed the main characteristic infrared absorption bands of cellulose ...

-
(The Italian Association of Chemical Engineering, 2019)Phenol and its derivatives are some of the organic pollutants found in wastewater and they pose health risks to human beings and animals if left untreated. This work investigates the use of modified Layered Double Hydroxide ...
-
(Elsevier, 2015-12)Thallium (Tl) is a highly volatile and toxic heavy metal regarded to cause pollution even at very low con-centrations of several parts per million. Despite the extremely high risk of Tl in the environment, limitedinformation ...
-
(University of Pretoria, 2019)Ion exchange and adsorption (can both be referred to as ‘sorption’) are widely used as purification and concentration methods in the nuclear industry. Various mathematic models have been developed to describe the mechanisms ...
-
(Nova Science Publishers, 2015)The paper presents a complete conspectus of ethylene-co-vinyl acetate (EVA) nanocomposites based on different types of nanostructured materials incorporated into EVA polymers. The three types of nanostructured materials, ...
-
(University of Pretoria, 2007-01-12)The aim of this study was to propose a nonlinear multiscale principal component analysis (NLMSPCA) methodology for process monitoring and fault detection based upon multilevel wavelet decomposition and nonlinear principal ...
-
(University of Pretoria, 2024-01-29)Nitrogen and phosphorus form the backbone of most lifeforms on earth, however, improper management of these nutrients has devastating effects on the environment. These effects can be lessened by the use of the anaerobic ...
