Extraction of Lysozyme by Hydroxyl-Functionalized Ionic Liquid Aqueous Two-Phase System

Extraction and separation of proteins by ionic liquid aqueous two-phase system.

A satisfactory protocol of protein extraction and separation has been established based on the ionic liquid aqueous two-phase system (IL-ATPS) for the purification of bioactive substances. Compared with the effects of eight different ionic liquids, 1-octyl-3-methylimidazolium bromide ([omim][Br]) was selected as the suitable ionic liquid. Based on the single-factor experiment, an initial serial...

Extraction and Process Conditions Optimization of Ficin by Ionic Liquid Aqueous Two-phase System

In order to research the application of [C4mim] Br-K2HPO4 ionic liquid aqueous two-phase system to extract ficin, the influence of reagents to the activity of ficin have been investigated. This study aimed to investigate the effects of species and concentration of the ionic liquid, the dosage of ficin, pH value and temperature on the partitioning behavior of ficin, respectively. Response surfac...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

Influence of process variables on extraction of Cefalexin in a novel biocompatible ionic liquid based-aqueous two phase system.

Despite the fact that ionic liquid-based aqueous two phase systems (ATPSs) have been widely studied for extraction purposes, the adequacy of biodegradable organic salts as salting out agents has been left unexploited. In this study, we investigated the ability of sodium-based organic salts in the formation of ATPS in the presence of a common ionic liquid, [C4mim]BF4. In the pioneering aspect of...
