(University of Eldoret, 2017)The aim of the study is to report the dyeing of textile fibres using the natural dyes extracted from the seeds of Bixa orellana Linn. Natural dyes derived from plant materials have proved to be important alternatives to ... -
EFFECT OF LIMING ON LEVELS OF POLLUTANT HEAVY METALS IN SOILS AND THEIR UPTAKE BY MAIZE IN UASIN GISHU AND TRANS-NZOIA COUNTIES, KENYA
(University of Eldoret, 2013)Soil contaminated with heavy metals from agricultural and industrial sources leads to unhealthy food. The metals enter the food chain and are consumed by humans. Phosphate fertilizers too contain undetermined amounts of ... -
ELECTROCHEMICAL TREATMENT OF TEXTILE DYE WASTE WATER BY ANODIC OXIDATION
(University of Eldoret, 2014)Textile factories such as Rift Valley Textile Limited (RIVATEX) in Eldoret Kenya produce large volumes of wastewater which is alkaline, highly coloured and has high chemical oxygen demand (COD) and can adversely affect ... -
THE EFFECTS OF AMENDED MOLASSES WASTEWATER ON THE GROWTH PROGRESS, NUTRITION AND YIELD OF Capsicuum annuum ON ACIDIC SOILS OF KENYA
(University of Eldoret, 2015)Little research work has been done especially on increasing effects of soil acidity on crop production due to long periods of chemical fertilizer use in North Rift region especially Uasin Gishu and Nandi Counties. Moreover, ... -
DETERMINATION OF LEVELS OF AFLATOXIN IN MAIZE SAMPLES: A CASE STUDY OF UASIN GISHU COUNTY
(University of Eldoret, 2014)The determination of levels of aflatoxins was done in Uasin Gishu County Kenya. Aflatoxins are compound produced by the two fungi; aspergillus flavus and aspergillus parasiticus. The main aflatoxins B1, B2, G1 and G2 have ... -
INVESTIGATION OF POLLUTANT LEVELS AND EFFICIENCY OF HEAVY METAL REMOVAL USING BROWN ALGAE (Sargassum sp) BIOSORBENT: A CASE STUDY OF MIGORI RIVER, KENYA
(University of Eldoret, 2013)ABSTRACT An increase in population initiating rapid industrialization has been found to consequently increase the effluents and domestic wastewater into the aquatic system. This has resulted in heavy metal pollution which ... -
CHEMICAL COMPOSITION OF ATTRACTIVE BLENDS IN SELECTED OCIMUM SPECIES TRADITIONALLY USED TO LURE HONEY BEES
(University of Eldoret, 2019)The success of sustainable beekeeping depends on possibility of establishing a bee colony. Low hive occupation rate has been identified as one of the prominent challenges facing beekeeping sector in addition to pest attacks, ... -
ISOLATION AND CHARACTERIZATION OF NEW COMPOUNDS FROM Strychnos henningsii AND THEIR ANTI-MALARIAL ACTIVITIES
(University of Eldoret, 2013)Traditional medicines play an important role in the management of common fever associated with malarial symptoms, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully ... -
SOLID-STATE THERMAL DESOLVATION AND STRUCTURAL STUDIES OF OXALIC ACID DIHYDRATE, ZINC ACETATE DIHYDRATE, COPPER (II) SULFATE PENTAHYDRATE AND NICKEL (II) SULFATE HEXAHYDRATE
(University of Eldoret, 2013)For many years it has been widely accepted that crystal dehydration can be related to internal crystal structure. However, there is very little empirical data or experiments on this work. This work makes an attempt to use ... -
