A review of hydrofluoric acid and its use in the car wash industry
(2012-09)
Hydrofluoric acid (HF) is a common ingredient in car wash cleaning solutions mainly because it is highly effective and relatively inexpensive. Particulate matter from brake pads and discs, tire wear, and abrasion of road ...
Spectrophotometric Determination of Iron (III) by New Analytical Reagents Derived from Coupling Arylhydroxylamine and Aryldiazonium salt
(2012)
A highly sensitive and selective spectrophotometric method is developed for the determination of iron(III) in aqueous solution withhydroxytriazenes. In this work, the effect of pH variation, the composition ...
Antibacterial and Antifungal activities of Novel hydroxytriazenes.
(2012-04-02)
In a search for new leads potent antimicrobial agents, an array of novel hydroxytriazenes i-xi were synthesized and characterized through their melting point, crystal shape, colour and elemental analysis. ...
Comparison of Chemical and Mineralogical Properties of Geophagic Materials from Taita and Mombasa, Kenya
(2012-10)
Geophagy is the deliberate consumption of soil and clay deposits by animals including man. The practice is widespread particularly in pregnant women in Africa. This study of geophagic soil from coast province in Kenya had ...
Gas-phase total oxidation of benzene, toluene, ethylbenzene, xylenes using manganese oxides and copper manganese oxide catalysts.
(American Chemical Society, 2012-05-17)
Volatile organic compounds (VOCs) continue to be the major source of direct and indirect air pollution. Here, cryptomelane-type octahedral molecular sieve (OMS-2) manganese oxide, amorphous manganese oxide (AMO), and mixed ...
