Perfluoroalkyl acids in selected wastewater treatment plants and their discharge load within the Lake Victoria basin in Kenya
(Environmental Monitoring and Assessment, 2015-04-11)
A major ecological challenge facing Lake Victoria basin is the influx of chemical contaminants from domestic, hospital, and industrial effluents. Determined levels of perfluoroalkyl acids (PFAAs) in wastewater and sludge ...
Chemicals of Emerging Concern in Surface and Wastewater: A Perspective of Their Fate Within the Lake Victoria Catchment Area of KenyaAbstract
(2020-01)
Rapid technological advancement in the pharmaceuticals and chemical industry has led to synthesis of compounds used for health/personal care and industrial products in large amounts. These chemicals of emerging concern ...
Adsorption of Caffeine and Ciprofloxacin onto Pyrolitically Derived Water Hyacinth Biochar: Isothermal, Kinetic and Thermodynamic Studies
(2006-09)
In this work, the adsorptive features of water hyacinth (Eichhornia crassipes) derived biochar for sequestration of
ciprofloxacin and caffeine from aqueous solution is reported. The isothermal behaviour, adsorption kinetics, ...
Derivatization Reactions and Reagents for Gas Chromatography Analysis
(Advanced Gas Chromatography, 2012-03-21)
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 ...
Residue levels and discharge loads of antibiotics in wastewater treatment plants ( WWTPs), hospital lagoons, and rivers within Lake Victoria Basin, Kenya.
(Environmental Monitoring and Assessment, 2016-08)
The detection of antibiotics in water systems has instigated great environmental concern due to the toxicological effects associated with these compounds. Their discharge into the environment results from the ubiquity of ...
Insights on adsorption of carbamazepine onto iron oxide modified diatomaceous earth: Kinetics, isotherms, thermodynamics, and mechanisms
(Environmental Research, 2020-01)
To ameliorate adsorbent recovery by an external magnetic field, naturally occurring diatomaceous earth (DE) was modified with iron-oxide, characterized and applied for adsorption of carbamazepine (CBZ) from synthetic ...
Assessment of heavy metals in benthic macroinvertebrates, water and sediments in River Isiukhu, Kenya
(Environmental Monitoring and Assessment, 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 ...
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 ...
