Xin Kang, Pan Jiao

Open publisher page 1 citations

Abstract

In a phosphoric acid medium of c (H 3PO 4) 1.8～4.2mol·L -1 , germanium(Ⅳ) reacts with the new chromogenic reagent DMOHPF in the presence of Triton X 100 to form an orange red complex, with its mole ratio of (Ge∶R) 1∶2 and having its absorption maxima at 505nm. The molar absorptivity ( e ) is found to be 1.8×10 5L·mol -1 ·cm -1 . Beer′s law holds in the range of 0 to 7μg of Ge(Ⅳ) per 25ml of solution. This method has been used satisfactorily in the determination trace amounts of germanium in tea and in some medicines.
