Abstract:
This work presents the results of studies for protein and metal separations from aqueous solutions by means of metal-chelating interactions using salt-polymer aqueous two-phase systems. Several polymer-chelates were synthesized and characterized. Polyethylene glycol (8000 M.W.) and sodium sulfate along with four different chelates (IDA, TED, Cm-TREN and L-ASP) coupled to monomethoxy polyethylene glycol (M-PEG), were used for the preparation of aqueous two-phase systems and the recovering of metals. The PEG-Chelators synthesized complexed with Cu⁺² Ni⁺² Co⁺² and Zn⁺² were used for the recovery of proteins from aqueous solutions. The influence of the pH, the chelated metal as well as the number of accessible histidine groups on proteins partitioning was investigated and found not to follow a linear relationship for all cases.
