EXTRACTIVE-SPECTROPHOTOMETRIC DETERMINATION OF VANADIUM(V) AS AN ION-ASSOCIATION COMPLEX WITH 4-(2-PYRIDYLAZ0)-RESORCINOALN D TETRABUTYLAMMONIUM PERCHLORATE
A simple and sensitive extractive- spectrophotometric method for thedeterrnination of trace amounts of vanadium(V) is reported. The method is based on the quantitative extraction of the anion complex of V(V) with 4-(2-pyridy1azo)-resorcinol with tetrabutylammonium perchlorate into chloroform, followed by spectrophotometric measurements at 554 nm. Beer's law is obeyed over the concentration ...

متن کاملDetermination of Perchlorate Ion With Tetraphenylarsonium Chloride
A detailed study of precipitation reaction of perchlorate ion with tetraphenylarsonium chloride is reported. Optimum conditions for quantitative precipitation of perchlorate ion were determined. A gravimetric and a spectrophotometric method for perchlorate ion are proposed. The spectrophotometric method is based upon dissolution of ( C.H.),AsClO. in acetonitrile and subsequent measurement of ab...
متن کاملDetermination of Iron Species by Combination of Solvent Assisted-Dispersive Solid Phase Extraction and Spectrophotometry
A simple, rapid and sensitive solvent assisted-dispersive solid phase extraction method was developed for the extraction of iron(II) prior to its spectrophotometric determination. The Fe(II) reacted with 2,4,6-tris(2-pyridyl)-1,3,5-triazine, neutralized with sodium dodecyl sulfate and extracted onto the fine particles of benzophenone which were formed upon rapid injection of a mixture of benzop...
