Kinetics of Copper Desorption from Regenerated Spent Bleaching Earth
(Department of Chemistry, Kenyatta University,Department of Chemistry, University of Nairobi,, 2009)Recent studies have shown that spent bleaching earth (SBE), a clayey waste from edible oil refineries, could be used to remove Cu from aqueous solutions. This could result in copper-laden material whose continual disposal ... -

The kinetics of haemopoietic differentiation assessed by in vitro bone marrow culture in endotoxin-treated and in anaemic calves
(University of Nairobi.School of Biological Sciences, 1980-07)Marrow aspirates from calves injected with Pseudomonas aeruginosa endotoxin showed an increased number of granulocyte/macrophage progenitor cells, and a reduced number of erythroid progenitor cells. On the other hand, ... -
Kinetics of single and multi-component sorption of Zn (ii) ions from aqueous solutions using a mineral of Kenyan origin
(Department of Chemistry, University of Nairobi. Nairobi. Kenya, 1990)The objective of this work was to test the efficacy and applicability of a micaceous mineral of Kenyan origin (herein referred to as Mica-K or the mineral) in the removal of Zinc ions from water and wastewater systems. -
Kirkinine, a New Daphnane Orthoester with Potent Neurotrophic Activity from Synaptolepis kirkii
(University of Nairobi, 2000)The bioassay-guided fractionation of a dichloromethane extract from the roots of Synaptolepis kirkii using neuronal viability as a model allowed the isolation of the new daphnane orthoester kirkinine (1a) as a powerful ... -
Knipholone anthrone from Kniphofia foliosa
(University of NairobiCollege of Biological and Physical Sciences, 1993-11)A new anthrone named knipholone anthrone was isolated from the stem of Kniphofia foliosa. Its structure was determined by spectral analysis as well as conversion to knipholone. -
Knipholone cyclooxanthrone and an anthraquinone dimer with antiplasmodial activities from the roots of Kniphofia foliosa
(Department of Chemistry, 2013)A new phenylanthrone, named knipholone cyclooxanthrone and a dimeric anthraquinone, 10-methoxy-10,7′-(chrysophanol anthrone)-chrysophanol were isolated from the roots of Kniphofia foliosa together with the rare naphthalene ... -
