Separation, Pre-Concentration, and Determination of Al(Iii) By Cloud Point Extraction As A Compact Method With Liquid Ion Exchange

Compact method of liquid ion exchange and cloud point extraction (cpe) was used as a sensitive green method for separating aluminum(iii) as ion pair association complex between janus green b as a large organic cation with al(iii) as metal anion complex (alcl4-) from nacl medium, the optimum conditions were studied, and for the higher extraction efficiency shows a method of extraction needed 0.5 m nacl in aqueous solution with 100 μg/10 ml of al(iii) ion. 0.5 ml non-ionic surfactant tritonx-100 and heating at 80 °c in an electrostatic water bath for 20 min as a heating time to form cloud point layer (cpl) as the addition phase to extract ion pair association complex formed in the aqueous phase. thermodynamic data for extraction al(iii) equal to δhex=92.530 kjmol-1, δgex=-63.263 kjmol-1, δsex=441.339 jmol-1k-1. likewise, this study included the effect of electrolytes, interferences, kind of surfactant, and kind of organic reagent as in stoichiometry studies. this method is applied for spectrophotometric determining for a(iii) in dissimilar samples.
