Determination of Trace Germanium in Purified Zinc Sulphate Solutions in Zinc Hydrometallurgical Process With Dual Wavelength Spectrophotometric Method

Wu Yushuang, Zhao Xinna (Powder Metallurgy Factory of Central-south University of Technology, Changsha 410083)  
The colorimetric system employed for the determination of Ge in zinc hydrometallurgic process in this paper is Ge-salicylfluorone-p-octyl polyethylene glycol phenyl ether (OP) with 1mol/ L HCl acidi- ty. With dual wavelength absorbance measurements to deduct the interference of highly concentrated zinc sulphate, trace Ce in purified zinc sulphate solution can be determined directly without pre-separation.
