Solvent extraction and spectrophotometric determination of gallium with Pyrocatechol Violet

Spectrophotometric determination of gallium(III) with rutin.

Solvent Extraction and Spectrophotometric Determination of Magnesium by Paratoly l-2-Thenohydroxamic Acid and Quinalizarin

Magnesium is extracted with a chloroform solution of N-p-tolyl-2- thenohydroxamic acid (PTTHA) from aqueous solution of pH 9.5 .Mg-PTTHA complex is colourless and the colour is developed by adding quinalizarin into the extract. lmax and e of the complex are 590nm and 2.8´103 Lmol -1cm-1respectively.Most common  ions do not interfere in the determination of magnesi...

Extraction - Spectrophotometric Determination of Palladium with Tetrabutyl Ammonium Iodide

A sensitive and selective extraction - spectrophotometric method for the determination of trace amounts of palladium is reported. The method is based on quantitative extraction of brownish tetrabutylammoium tetraiodopalladium (II) ion pair into a small valume of chloroform at pH 1.3-12.0, followed by spectrophotometric measurements. The Beer's law is obeyed over the range 0.02-1.09 <em...

A Novel Magnetic Nano-hybrid as a Sorbent for Solid-phase Extraction-spectrophotometric Determination of Methyl Violet 10B Dye

In this research, the magnetite polystyrene maleic anhydride (MPSMA) was synthesized and structure and morphology characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy techniques. The obtained nano-structured inorganic material was employed as a novel magnetic nanosorbent for separation and pre-concentration of Methyl violet (10B) dye from aqu...
