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...

متن کاملComparison of solvent mixtures for pressurized solvent extraction of soil fatty acid biomarkers.
The extraction and transesterification of soil lipids into fatty acid methyl esters (FAMEs) is a useful technique for studying soil microbial communities. The objective of this study was to find the best solvent mixture to extract soil lipids with a pressurized solvent extractor system. Four solvent mixtures were selected for testing: chloroform:methanol:phosphate buffer (1:2:0.8, v/v/v), chlor...
متن کاملEvaluation of the copper(II) complexing ability of ultrafiltered humic acid by the solvent extraction method.
A commercial humic acid dissolved in water was fractionated to nine samples by means of ultrafiltration (UF); the nominal molecular weight used for UF membranes was 1 k-200 kDa. Concerning the nine samples, copper(II) complexing capacities (CuCC) and conditional stability constants (beta) of the formed copper(II) complexes were measured by a solvent extraction method. A total organic carbon (TO...
متن کاملPurification of Wet Process Phosphoric Acid by Solvent Extraction using Cyclohexanol
Solvent extraction using organic solvents is an important technology for the purification of wet process phosphoric acid (WPA). In this study, the purification process of WPA, using a new type of solvent extraction system, cyclohexanol diluted in kerosene, was investigated. The equilibrium phase diagram of the system H3PO4 H2Osolvent mixtures at 313.2K was obtained. The effects of extraction ...
