Adsorption of copper ions from water onto fish scales derived biochar: Isothermal perspectives
(Journal of Materials and Environmental Science, 2020)
In this work, Tilapia (Oreochromis niloticus) fish scales were used for the development
of an economical biochar (FSB) by slow pyrolysis at 600 oC. The FSB was characterized
using energy dispersive x-ray (EDX), x-ray ...
Assessment of Levels of Nutrients in Selected ALVs at Different Harvesting Stages and Locations of Production in Western Kenya
(International Journal of Biochemistry Research & Review, 2019-04)
Proper nutrition contributes to declines under-five mortality rates and improves the productivity of adults. Addressing nutritional problems requires adequate information on the diets of individuals and populations. African ...
Single and binary adsorption of sulfonamide antibiotics onto iron‑modifed clay: linear and nonlinear isotherms, kinetics, thermodynamics, and mechanistic studies
(Springer, 2018)
Iron-modifed raw kaolinite clay (Fe-MC) was synthesized by co-precipitation method, characterized, and then applied as a
low-cost adsorbent to sequester sulfachloropyridazine (SCP) and sulfadimethoxine (SDM), emergent ...
Errors in parameters estimation using linearized adsorption isotherms: sulfadimethoxine adsorption onto kaolinite clay
(Chemical Science International Journal, 2018-08-29)
In this work, an isothermal investigation of the adsorption of sulfadimethoxine from aqueous solution onto clay mineral (kaolinite) using batch equilibration method is reported. The equilibrium data were modelled using ...
Influence of Nitrogen Fertilisation on Red Spider Mites (Oligonychus coffeae Nietner) and Overhead Volatile Organic Compounds in Tea (Camellia sinensis)
(International Journal of Tea Science Vol 13, No. 1&2 (2017) : 52-59, 2017)
Nitrogen fertilisation influences tea yields, quality and pests infestation levels. Red spider mites reduce tea production in western Kenya during prolonged droughts. Nitrogen fertiliser use maybe an agronomic practice ...
Sensoring Gaseous Ammonia using Cation Exchanged Faujasite-X Zeolite
(International Journal of BioChemiPhysics,, 2010)
work presents a method that uses cheap, thermally stable and reusable cation exchanged solid zeolites to
detect gaseous ammonia. Here, 24 separately exchanged Cu2+ and Co2+ cations per unit cell of 1.23 Si/Al
Faujasite-X ...
Influence of land use practices on water physicochemical parameters and nutrients loading along the Mara River of East Africa
(AcademicJournal, African Journal of Environmental Science and Technology, 2018-07)
Mara River originates from the Mau Forest and traverses through landscapes with varying activities. Over the years, Mara River Basin has witnessed population increase, accompanied with conversion of forestlands into ...
Variations of Fatty Acids Levels in Young Shoots of Clonal Tea With Location of Production and Nitrogenous Fertilizer Rates in the Kenya Highlands
(Journal of Agricultural Science and Technology, 2012)
Tea leaves contain unsaturated fatty acids, key precursors of volatile compounds contributing to tea aroma quality. Tea is cultivated in areas with diverse environmental conditions. Nitrogenous fertilizers influence tea ...
Assessment of water quality of the Nyando River (Muhoroni-Kenya) using the water quality index (WQI) method
(Research gate, 2019)
The quality of a river water is described by the levels of physico-chemical and microbiological parameters. The aim of the study was to determine the water quality of NyandoRiver water from four sampling stations (Muhoroni, ...
Simultaneous quantification of acetaminophen and tryptophan using a composite graphene foam/Zr-MOF film modified electrode
(New Journal of Chemistry, 2020)
