Aluminium Nitrate As External Absorbent In The Microdetermination Of Carbon And Hydrogen In Organofluorine Compounds
( Qatar University , 1994 , Article)Silica gel loaded with saturated A1(NO3)3- 10. H2O solution proved to be an efficient absorbent for the elimination of the interference of fluorine in the microdetermination of carbon and hydrogen in organofluorine compounds. ... -
Crystal hydration and vacancy enhanced isotopic exchange reactions in Heterogeneous solid - liquid systems
( Qatar University , 1994 , Article)The rate of some heterogeneous isotopic exchange reactions can be enhanced by the simultaneous hydration of the solid participating in the exchange process. The results presented here show that the concomitant hydration ... -
Effect Of Adsorption Of Tetrabutylammonium Chloride In Polarography
( Qatar University , 1994 , Article)The polarographic behaviour of chromate, iodate and zinc has been investigated in the presence of different concentrations of tetrabutylammonium chloride in 0.1 M Na2SO4 and 0.1 M H2SO4. The effect of organic compound on ... -
Iodometric microdetermination of phosphorus in organic compounds by use of An amplification reaction
( Qatar University , 1994 , Article)A high chemical amplification method is described for the iodometric microdetermination of phosphorus in organic compounds. This method depends on combustion by the oxygen flask, absorption of the combustion products in ... -
Separation and preconcentration of malathion and azamethiphos by Unloaded polyurethane foams
( Qatar University , 1994 , Article)The feasibility of using unloaded polyether type polyurethahe foams for the extraction and separation of malathion and azamethiphos in batch and column operations has been examined. The effects of pH, ionic strength, shaking ...
