Spectrophotometric Determination of Cobalt by Solvent Extraction With Isonitrosoacetophenone

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...

Extraction-spectrophotometric Determination of Cobalt in Soils by the Application of Iodine Nitrotetrazole Chloride (int)

An extraction-spectrophotometric method for cobalt determination in soils by the application of iodine nitrotetrazole chloride (INT) was developed and compared to atomic absorption spectrometry (AAS). The method investigated characterized with expressivity, selectivity and satisfactory accuracy.
