摘要
An aqueous biphasic extraction system was designed using different molecular weights of polyethylene glycol and concentrated salt solutions of sodium sulphate to separate the heavy metals, Hg, Tl and Pb from Li irradiated Au matrix. All the four elements could be separated from one another by this extraction process by simply optimizing the salt rich phase, the pH of the salt rich phase and the molecular weight of the polymer rich phase.
