Assessment of heavy metals in benthic macroinvertebrates, water and sediments in River Isiukhu, Kenya
(Environmental Monitoring and Assessme, 2019-10-16)
A major ecological challenge facing freshwater resources such as rivers is the influx of chemical contaminants from anthropogenic sources. A report on the levels of heavy metals, namely Zn, Cu, Cr, Cd and Pb in benthic ...
Simulation guided prediction of zeolites for the sorption of selected anions from water: Machine learning predictors for enhanced loading
(Journal of Molecular Liquids, 2022-06-01)
The development of highly efficient adsorbents, especially those that can harvest anions like CrO42−, AsO43−, NO3– and PO43−, is one of the principal challenges in the water treatment field. The current study utilized a ...
Biodegradation of carbofuran in soils within Nzoia River Basin, Kenya
(Journal of Environmental Science and Health, Part B, 2015-04)
Carbofuran (2,3-dihydro-2,2-dimethylbenzofuran-7-yl methylcarbamate) has been used within the Nzoia River Basin (NRB), especially in Bunyala Rice Irrigation Schemes, in Kenya for the control of pests. In this study, the ...

Comparative studies in electrochemical degradation of sulfamethoxazole and diclofenac in water by using various electrodes and phosphate and sulfate supporting electrolytes
(Journal of Environmental Science and Health, Part A, 2016-06-23)
In this study, the electro-oxidation capacities of Na2SO4 and potassium phosphate buffer supporting electrolytes were tested and compared for destruction of the sulfamethoxazole (SMX) and diclofenac (DCF) on platinum (Pt) ...
Role of pore chemistry and topology in the heavy metal sorption by zeolites: From molecular simulation to machine learnin
(Computational Materials Science, 2021-04-23)
Zeolite frameworks can provide pores that enable selective heavy metals sorption, making these materials promising for energy-efficient heavy metals capture. In the present study, the adsorption of hazardous heavy metal ...

The objective of the study was to examine spatial and temporal levels of heavy metals in water,
sediments and fish in Sosiani River. This study was an experimental design approach in which a scientific analysis
was done ...
Fish Tissue Bio-concentration and Interspecies Uptake of Heavy Metals from Waste Water Lagoons
(Journal of Pollution Effects & Control, 2016-01)
Fish products may be important vectors of human exposure to heavy metals. However the understanding of how heavy metals bioconcentrate in different fish species (sp.) through contaminated environments such as wastewater ...
Derivatization Reactions and Reagents for Gas Chromatography Analysis.
(Advanced Gas Chromatography - Progress in Agricultural, Biomedical and Industrial Applications, 2012-03)
Derivatization reactions are meant to transform an analyte for detectability in Gas Chromatography (GC) or other instrumental analytical methods. Derivatization in GC analysis can be defined as a procedural technique that ...
