摘 要:<正> A dual system and dual wavelength spectrophotometry(DSDWS)used to simultaneously determine Zrand Hf were proposed.《Zr(Hf)-xO-CTMAB》and《Zr(Hf)-CAB-CDMAA-Triton X-100》were chosenas a pair of chromophoric systems.The difference of chromophoric behaviours between Zr and Hf is in-creased by the addition of hydrogen peroxide as masking agent and by adjustment of acidity.The apparentmolar absorptivities of Zr and Hf are 2.0×105 and 5.0×104 L·mol-1·cm-1respectively.The proce-dure is simple and rapid.
