Zirconium and Hafnium

The extraction chromatographic behavior of zirconium(IV) and hafnium(IV) was investigated using di(1-methylheptyl) methylphosphonate (DMHP) as a stationary phase in the media of hydrochloric acid-ammonium chloride by a batch method. Through a log-log analysis and the IR spectra the extractable species has been proposed to be (DMHPH+)2ZrC162-and (DMHPH+)2HfC162-. The quantitative separation of Zr(IV) and Hf(IV) with ratios of 1:1 to 100 :1 from each other has been achieved by DMHP-extraction chromatography.
