Insight into the Liquid–Liquid Extraction System AuCl4−/HCl/A327H+Cl− Ionic Liquid/Toluene

نویسندگان

چکیده

The ionic liquid A327H+Cl− is generated by reaction of the tertiary amine A327 (industrial mixture tri-octyl and tri-decyl amines) hydrochloric acid solutions. In this study, extraction Au(III) under various variables, including metal concentrations, was investigated. Results indicate that A327H+AuCl4− formed an exothermic (ΔH° = −3 kJ/mol) in organic solution. Aqueous strength influences formation constant values, specific interaction theory (SIT) used to estimate coefficient between AuCl4− H+. Gold (III) stripped using thiocyanate media, from strip solutions, gold precipitated as nanoparticles.

New Insight into the Relation between Adiponectin and Diabetes

Diabetes mellitus is a group of metabolic diseases. Insulin resistance is defined as a state that needs more insulin to get the biological effects achieved by a lower amount of insulin in the normal state. Several molecules which are secreted through adipocytes have been involved in insulin resistance and type 2 diabetes mellitus. Adiponectin as a 244 amino acid protein is exclusively expressed...

Extraction of pertechnetates from HNO3 solutions into ionic liquids

The extraction of pertechnetate ions from aquous solutions containing various concentrations of nitric acid into hydrophobic ionic liquids (ILs) has been examined at 25, 50 and 70 °C. The results show that the distribution ratio of Tc (DTc) between both phases weakly depends on the temperature and HNO3 concentration when IL's with relatively short aliphatic chains are used. The DTc obtained for...
