Liquid Ion Exchange Application for Micro Amount Separation and Determination of Ca(II) and Mg(II) as Anions Species with EDTA

Abstract

Extracted Mg(II) and Ca(II) each one alone after combined with EDTA (H 3 Y -) as (MgHY -) and (CaHY -) after preparing ion pair complexes according to liquid ion exchange method by using Cinchonine (CK) after changing to liquid ion exchanger HCK + ;Cl -in HCl medium, spectrophotometric studies showed that the ion pair magnesium complex HCK + ;MgHY -had a wave length for maximum absorbance of λ max =241nm, but the maximum absorbance for calcium HCK + ;CaHY -was λ max =278nm to determine the remaining quantity of Mg(II), the Eriochrome black T method was used, but for Ca(II) the crown ether DB18C6 method was used as new spectrophotometric method. Limitations to the study include optimum conditions for extraction ions in this study show a need for 1M HCl for Mg(II) and 0.8M HCl for Ca(II), to be present 100µg for each ion, 0.08M EDTA for Mg(II) and 1.0M EDTA for Ca(II), 1×10 -4 M CK, after shaking for 10 min.

Acrylonitrile-Containing Copolymer Synthesis and Magnesium Ions Adsorption of the Copolymer

“…Cloud point with EDTA is a suitable method for the extraction of Mg 2+ ions. Prunus Dulcis L. barks modified with EDTA were found to have high biosorption capacity (Canlıdinç, 2022;Jawad, et al, 2017). Examples of modification of polyacrylonitrile have been reported (Arsalani and Hosseinzadeh, 2005).…”

The Fundamentals and Recent Applications of Micellar System Extraction for Nanoparticles and Bioactive Molecules: A Review

“…MSE has been widely studied recently as an environmentally fast, selective, accurate, and green approach to preconcentration and separation of several solutes, providing many other benefits over previous solvent extraction. The MSE is dependent on micelle mediating agents' ability to form ML in water when heated above a certain temperature, known as the critical temperature (CT) [18][19][20].…”

Aspirin in Food Samples for Separation and Micro Determination of Copper(II) Using Cloud Point Extraction/Solvation Method

“…Different techniques were examined for copper pre-concentration and separation in different environmental and organic matrices. Methods as solvent micro extraction [7,8], also used another ion [9], solid phase extraction (SPE) [10], inductively coupled plasma mass spectrometry [11], ion chromatography [12], flame and graphite furnace atomic absorbing spectrometry [13] and spectrophotometric methods [14][15] and cloud point extraction (CPE) [16], [17] were described for this purpose. Nevertheless, extraction methods such as LLME or SPE, have most amounts of biological solvent that are particularly toxic volatile, flammable and destructive to the surroundings [18], or large volumes of eluents to guarantee the whole backextraction of the interested analytes, correspondingly.…”
