微波辅助聚乙二醇-硫酸铵双水相体系萃取铂、钯及非等温动力学
Microwave-promoted Extraction of Pt and Pd from Aqueous Biphase System of Polyethyleneglyol/(NH4)2SO4 and the Non-isothermal Kinetics of Reaction
【Abstract】 Microwave irradiation technique was used to promote the extraction processes of bromide complex anions of Pt(Ⅱ) and Pd(Ⅱ) from aqueous biphase system of polyethyleneglyol/(NH4)2SO4. The results showed that under microwave irradiation the distribution ratio of metals, extraction capacity and extraction ratio increased significantly as compared with conventional extraction technique. Under microwave irradiation the extraction ratio of Pt or Pd achieved 100.0% and 99.6%, respectively. The non-isothermal kinetics on the extraction reaction also approved the enhanced extraction rate.
