Improved Extraction-Separation of Lanthanum/ Europium Ions by Bis(2-ethylhexyl)phosphoric Acid Using 12-Crown-4 as an Ion Selective Masking Agent
The extraction-separation of lanthanum and europium ions with bis(2-ethylhexyl) phosphoric acid (DEHPA) in cyclohexane was improved by adding 12-crown-4 (12C4) to the aqueous phase as a masking agent. In the presence of this crown ether the extraction curve of lanthanum ions versus pH shifts to the higher pH region, while the curve is not influenced for the europium ions. Consequently the s...
متن کاملCytotoxic Activity of Bioactive Compound 1, 2- Benzene Dicarboxylic Acid, Mono 2- Ethylhexyl Ester Extracted from a Marine Derived Streptomyces sp. VITSJK8
Marine Streptomyces are prolific producers of majority of bioactive secondary metabolites which are used in pharmaceutical industry as effective drugs against life threatening diseases. The cytotoxic activity of the pure compound 1, 2- benzene dicarboxylic acid, mono 2- ethylhexyl ester (DMEHE) from marine derived actinomycete Streptomyces sp. VITSJK8 was investigated against mouse embryonic fi...

متن کاملSolvent 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 کاملComparative Study on Pantothenic Acid Separation by Reactive Extraction with Tri-n-octylamine and Di-(2-ethylhexyl) Phosphoric Acid
Vitamin B5 was isolated from yeast in 1933, and a few years later from liver, by R.J. Williams. The main role of pantothenic acid in cells is the synthesis of coenzyme A, as well as the synthesis and metabolism of proteins, carbohydrates and fats. Regarding the human body, this compound is involved in the health of the digestive, nervous, circulatory, and skeletal systems, skin and hair, as wel...
