The use and application of synthetic zeolites for ion exchange, adsorption and catalysis has shown enormous potential in industry. In this study, X-ray fluorescence (XRF) analysis was used to determine Si and Al in fly ash (FA) precipitates. The Si and Al contents of the fly ash precipitates were used as indices for the alkaline hydrothermal conversion of(More)

The behavior of an amperometric organic-phase biosensor consisting of a gold electrode modified first with a mercaptobenzothiazole self-assembled monolayer, followed by electropolymerization of polyaniline in which acetylcholinesterase as enzyme was immobilized, has been developed and evaluated for organophosphorous pesticide detection. The voltammetric(More)
A South African national perspective of mining related water research needs published by the Water Research Commission stated that the mining industry has a huge potential to impact negatively on the environment and that adequate measures to address this problem are not available. Sources of water related pollution originate from underground and open cast(More)
OBJECTIVE To evaluate the biological activities of Combretum erythrophyllum (C. erythrophyllum) leaf extracts against infectious diseases' pathogenesis and their cytotoxicity potentials. METHODS Powdered leaf material (300 g) of C. erythrophyllum was extracted (1:10 w/v) using acetone to obtain the crude extract. Liquid-liquid fractionation was performed(More)
