2,2'-Biquinonyl spectrophotometric determination of microamounts of copper in the presence of macroamounts of platinum group elements: 2,2'-Biquinonyl spectrophotometric determination of microamounts of copper in the presence of macroamounts of platinum group elements. Yan, Xi (Jinchuan Inst. Nickel Cobalt, Peop. Rep. China). Lihua Jianyan, Huaxue Fence, 22(2), 92 (Chinese) 1986. CODEN: LJHFE2. DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Trace Cu was detd. in the presence of large amt. of Pt-group metals by spectrophotometry. Cu was extd. 15752-05-3 and 7440-50-8 which are cas registry numbers are also used here. by 0.02% 2,2'-biquinonyl soln. (in isopentanol-1,2-dichloroethane) and was detd. by measuring the absorbance at 544 nm against the reagent blank. Beer's law was obeyed for 0-25 mg Cu/5 mL. Au > 0.05 mg, Pt > 10 mg, Pd > 20 mg, and Fe3+ ~ 10 mg interfere in detn. of 5 mg Cu. Cu was detd. in RhCl3, (NH4)2RuCl4, and (NH4)3IrCl6. .
