Reverse phase extraction chromatographic separation of osmium(VIII) with N-n-octylaniline
A trace level concentration of osmium(VIII) has been quantitatively extracted from 1.0 M hydrochloric acid with 0.087 M N-n-octylaniline as a stationery phase on silica gel. Osmium(VIII) has been eluted with 5.5 M, 25 mL hydrochloric acid and determined by spectrophotometric method. Various parameters influencing the extraction, such as acid concentration, reagent concentration and flow rate ha...
متن کاملN-octyl-modified magnetite NPs for optimization of solid phase extraction for trace analysis of phenytoin in real samples
objective: Phenytoin is an anti-seizure medication used to treat epilepsy, as well as to control arrhythmias (irregular heartbeat) and to treat migraine headaches and nerve pain. It is recommended to determine the amount of this drug in the blood to control the seizure and prevent its toxicity. In the present study, a sensitive and simple procedure based on the dispersive solid phase extraction...
متن کاملInvestigation of the ion-pair formation of palladium(II) with N-n-octylaniline by solvent extraction from weak organic acid media
The use of N-11-octylaniline in xylene for extraction of palladium(II) from salicylate media is studied. The extraction system is studied as a function of equilibration time, diluent, pH, metal and extractant concentrations. Experimental data have been analyzed graphically to determine the stoichiometry of extracted species. It was found that palladium(II) was extracted into the organic phase b...
متن کاملReverse phase partition chromatographic separation of vanadium with N-n-octylaniline on silica gel
A selective, sensitive, less expensive and more precise method was developed for the separation of vanadium [VO] using Nn-octylaniline (liquid anion exchanger) coated silica gel as stationary phase. The quantitative extraction of vanadium was found with 0.065 mol/L N-n-octylaniline and 0.009 to 0.02 mol/L of sodium malonate at pH 10.5. The extracted vanadium ion was eluted from the column with ...
