Immobilized Metal-ion Affinity Partitioning in Polyethylene Glycol - Hydroxypropyl Starch Aqueous Two-Phase Systems

摘要

A new synthesis route was proposed to prepare iminodiacetic acid-Polyethylene glycol (IDA-PEG) for immobilized metal ion affinity partitioning. The Cu~2+ content combined with IDA-PEG was 0.5mol/mol PEG. Using Cu(II)-IDA-PEG, affinity partitioning behavior was studied.
