Associations between dietary salt, potassium and blood pressure in South African adults: WHO SAGE Wave 2 Salt & Tobacco
(Elsevier, 2017)Background & aims In June 2016, South Africa implemented legislation mandating maximum sodium levels in a range of processed foods with a goal of reducing population salt intake and disease burden from hypertension. Our ... -
The behaviour of potassium and sodium species during the thermal treatment of a demineralized Highveld coal
(North-West University, 2011)A series of experiments was conducted to investigate the potential influence of pre- and post adding of catalysts to a demineralized coal char. The catalysts were chosen according to yield better catalytic activity and be ... -
Extraction of K, AI and Ti containing compounds from ash produced by low temperature combustion
(North-West University (South Africa), 2019)South African coal samples can contain up to 30% aluminium oxide which is constituted in the mullite and insoluble aluminium silicate mineral phases. This suggests that coal ash, produced in power plants or thermal processing ... -
FACTSAGE™ thermo-equilibrium simulations of mineral transformations in coal combustion ash
(SAIMM, 2018)The aim of this investigation is to report on the influence of operating conditions, and of additives such as potassium carbonate, on the slagging behaviour of South African coal. This was done using a FACTSAGE™ model that ... -
Getting rid of the unwanted: highlights of developments and challenges of biobeneficiation of iron ore minerals—a review
(Springer, 2014)The quest for quality mineral resources has led to the development of many technologies that can be used to refine minerals. Biohydrometallurgy is becoming an increasingly acceptable technology worldwide because it is cheap ... -
The influence of potassium carbonate and potassium chloride during heat treatment of an inertinite–rich bituminous char
(North-West University, 2012)Thermogravimetry, coupled with a mass spectrometer (TG-MS) was used to investigate the catalytic effect potassium carbonate (K2CO3) and potassium chloride (KCl), on the char conversion and the product gas composition of ... -
Monitoring the South African population’s salt intake: spot urine v. 24 h urine
(Cambridge Univ Press, 2018)Objective The present study set out to determine whether morning spot urine samples can be used to monitor Na (and K) intake levels in South Africa, instead of the ‘gold standard’ 24 h urine sample. Design Participants ... -
Salt and potassium intake among adult Ghanaians: WHO-SAGE Ghana Wave 3
(BMC, 2020)Though Ghana has high hypertension prevalence, the country lacks current national salt consumption data required to build and enhance advocacy for salt reduction. We explored the characteristics of a randomly selected sub ... -
Sodium and potassium intake in South Africa: an evaluation of 24-hour urine collections in a white, black, and Indian population
(Elsevier, 2016)Limited number of studies on salt intake has been conducted in the South Africa. The present study established the sodium and potassium excretion (24-hour urine collection) of three different South African populations. In ... -
Sodium intake in South Africa : an analysis of food supply, 24-hour excretion and blood pressure in a tri-ethnic population
(North-West University (South Africa) , Potchefstroom Campus, 2017)Introduction: Currently, 1.13 billion people in the world have increased blood pressure. Low and middle income countries, including South Africa, contribute significantly to this number. The burden caused by hypertension ...
