Assessment of photo-oxidative alterations to natural organic matter in water using fluorescence excitation emission matrices and liquid chromatography-organic carbon detection techniques
Bosire, G. O.; Ngila, J. C. (RSC, 2015)Fluorescence excitation emission matrices (FEEMs) and liquid chromatography-organic carbon detection (LC-OCD) are relatively novel techniques currently used for analysing natural organic matter (NOM) in water. Regardless ... -
Comparison of Three Solid Phase Materials for the Extraction of Carboxylic Acids from River Water Followed by 2D GC × GC-TOFMS Determination
Bosire, G. O.; Ngila, J. C.; Parshotam, H. (Hindawi Publishing Corporation, 2016)The extraction and determination of aliphatic and aromatic carboxylic acids as well as their influence on the aromaticity and molecularity relationship of natural organic matter (NOM) in water are reported in this study.Three ... -
Experimental and Theoretical Characterization of Metal Complexation with Humic Acid
Bosire, G. O.; Kgarebe, B. V.; Ngila, J. C. (2016)This study investigated the bonding of calcium and magnesium to specific sites in humic acid as a function of pH, temperature, and trace metal concentrations. Other metals were investigated but not in detail. Using a ... -
Geochemical scaling potential simulations of natural organic matter complexation with metal ions in cooling water at Eskom power generation plants in South Africa
Bosire, G. O.; Ngila, J. C.; Nkambule, Thabo T.I. (2018-09-26) -
Zn and Pb marking of Ca binding to humic substances and PHREEQC speciation simulations
Bosire, G. O.; Ngila, J. C. (IWA Publishing, 2016)Power generating companies using and recycling cooling water usually experience deposition of insoluble salts on pipes carrying the water, leading to scaling problems. By controlling parameters that optimize competitive ...
