摘 要: 在0.36mol/LHCl介质中,有溴化十六烷基三甲基铵存在下,Zr(Ⅳ)与柠檬酸及溴邻苯三酚形成成胶束混配有色配合物,该配合物最大吸收波长在470nm,摩尔吸光系数为6.64×104L·mol-1·cm-1.锆量在0~0.80mg/L范围内符合比尔定律。方法用于铝合金中微量锆的测定,结果满意。 In the medium of 0.36mol/L HCl,Zirconium(Ⅳ)reacts with bromopgallol red and Citric acid to form a colour complex of miceller mixed ligand in the presence of cetyltrimethylammonium bromide.The multicomponent complex exhibits maximum absorption at 470 nm with a molar absorptivity of 6.64×10 4L·mol -1 ·cm -1 .Beer′s law is obeyed in the range of 0~0.80mg/L for Zirconium..The proposed method has been applied to the determination of trace Zirconium in aluminium alloy with satisfactory results.
