摘要
研究了7-(4-安替吡啉偶氮)-8-羟基喹啉与锆(Ⅳ)的显色反应条件。结果表明:在pH为4的邻苯二甲酸氢钾缓冲溶液中,7-(4-安替吡啉偶氮)-8-羟基喹啉与锆(Ⅳ)形成一种橘黄色的络合物,其最大吸收峰位于480nm处,表观摩尔吸光系数为3.43×104 L·mol-1·cm-1,在25mL溶液中,锆质量在0~40μg范围内符合比尔定律。
The conditions of color reaction of zirconium(iv)with 7-(4-antipyrinylazo)-8-hdroxyquinoline were studied. The results show that zirconium(Ⅳ) reactes with 7-(4-antipyrinylazo)-8-hdroxyquinoline in the medium of potassium hydrogen phthalate buffer solution at pH 4.0 to form an orange yellow complex with maximum absorption wavelength at 480 nm, the apparent molar absorption coefficient being 3.43 × 10^4 L. mol-1 . cm 1. Beers)law is obeyed in the range of 0-40/Lg of zirconium(Ⅳ) mass in the 25 mL solution.
