“…[9-10] However solvent extraction processes have become major purification operations in practice [11][12][13] There are a few research reports on the use of a solvent extraction approach to recover Fe (III) from chloride solutions; the solvent includes various amines and quaternary ammonium salts; Extraction using immiscible solvents containing carbonyl group or Polyethers give very good results but it dissolves to higher rate starting from 6 N concentrations hydrochloric acid. [14][15][16][17][18][19] The present work examines the possibility of iron (III) separation from hydrochloric acid solution by solvent extraction using MIBK at various initial metal concentrations and MIBK ratios.…”

In this study Methyl Isobutyl Ketone (MIBK) and acetophenone (Methyl Phenyl Ketone) are presented as suitable agents for removal of Fe(III) from concentrated hydrochloric acid solutions. An extensive study applying 4 parameters was carried out: Time (5, 10,15,20,30 and 60 minutes), Stirring rate (200, 300, 400 and 500 r.p.m), Solvent to HCl Ratio (5%, 10%, 14% and 16%), and initial concentration of Fe ions in crude HCl (95.24, 126 ppm, 330 ppm and 1955 ppm).The best Condition was found to be 30 min-400 r.p.m-14 %. The distilled water was used to strip Fe ions out of MIBK; In order to get most of the MIBK dissolved in both the concentrated HCl and water. Diluents were used such as benzene, kerosene and xylene. Xylene gives better recovery of about 96%.

The selective extraction of metals from aqueous solutions is a very important stage in the hydrometallurgical processing of metallic waste. Leach solutions are usually a multicomponent mixture. The main impurity of aqueous solutions obtained after leaching using inorganic acids is iron. In this work, the membrane separation of iron(III) from nickel(II), cobalt(II), and lithium(I) was studied. The facilitated transport of metal ions using polymer inclusion membranes (PIMs) with tetrabutylammonium bromide (TBAB) as an ion carrier under various conditions was analyzed in detail. Several factors, such as the ion carrier concentration in the membrane as well as the effect of the inorganic acid concentration in the source/receiving phases on the kinetic parameters, were investigated. The results show that ionic liquid TBAB is a very selective ion carrier of Fe(III) towards Ni(II), Co(II), and Li(I).

“…The protein-carbohydrate interactions are important for immunology, biosynthesis, pharmacology, medicine, and cosmetic industry [17][18] . Thus, the properties of amino acids in aqueous-carbohydrate solutions are essential for understanding the chemistry of biological systems [19][20][21][22] . Direct study of solute/solvent interactions is difficult due to complex conformation of biological macromolecules 5 .…”
