Spectrophotometric Determination of cobalt (II) in low concentrations using hydroxytriazene as selective chelating agents
(2011-12)
The present work describes a selective, rapid and simple spectrophotometric method for the determination of cobalt (II) at trace levels using some selected hydroxytriazene. The method is based ...
Spectrophotometric determination of cobalt (ii) in low concentrations using hydroxytriazene as selective chelating agents.
(2011-12)
The present work describes a selective, rapid and simple spectrophotometric method for the determination of cobalt (II) at trace levels using some selected hydroxytriazene. The method is based on the reaction of hydroxytriazene ...
Analyses of geophagic materials consumed by pregnant women in Embu, Meru and Chuka towns in eastern province, Kenya
(2011)
Geophagy is the deliberate consumption of soil and clay deposits by animals, including man. During pregnancy all the nourishment needed by the developing fetus comes from the mother, either the food she eats or the supplement ...
Synthesis and insecticidal activities of some selected hydroxytriazenes. Journal of Environmental Chemistry and Ecotoxicology
(2011-10)
Eight hydroxytriazenes were synthesized and then subjected to spot tests. The composition of these hydroxytriazenes was analyzed using elemental analysis and their physical characteristics like melting point, crystal shape ...
Enhancement of the photo degradation of N-nitrosodimethylamine in water using amorphous and platinum manganese oxide catalysts
(ELSEVIER, 2011-01-25)
The enhancement of the photodegradation of toxic N-nitrosodimethylamine (NDMA) in water using amorphous manganese oxide (AMO) and platinum manganese oxide (Pt/Mn3O4) catalysts was investigated. Characterization of the ...
Nonthermal synthesis of three-dimensional metal oxide structures under continuous-flow conditions and their catalytic applications
(American Chemical Society, 2011-10-25)
Continuous-flow synthesis of one-dimensional (1D) metal oxide nanostructures and/or their integration into hierarchical structures under nonthermal conditions is still a challenge. In this work, a nonthermal, continuous-flow ...
Light-assisted synthesis of metal oxide heirarchical structures and their catalytic applications
(American Chemical Society, 2011-02-18)
Short reaction times and morphology control in the synthesis of inorganic materials under nonthermal conditions remain a challenge. Herein we report a rapid, self-templating, and nonthermal method based on ultraviolet light ...
Self-assembly of manganese oxide nanoparticles and hollow spheres. Catalytic activity in carbon monoxide oxidation†
(2011)
Reactions between MnSO4 and KMnO4 in the presence of carboxylic acids provide a facile, one-pot route to nanostructured manganese oxides with high surface areas. Acetic and propionic acid induce formation of hierarchical ...
Chemical And Mineralogical Analysis of Geophagic Materials Consumed By Pregnant Women In Eastern Nairobi And Nyanza Provinces In Kenya
(2011)
Geophagy is the purposeful or deliberate consumption of Earth and clay deposits by animals, including man. It is a special type of pica, which is defined as the craving and subsequent consumption of non-food substances. ...
