摘要
在0.5mol/L硫酸介质中,表面活性剂OP作用下,钛与2-羟基-3-甲氧基苯基荧光酮(HMPF)形成红色的配合物,其最大吸收峰位于536nm,表观摩尔吸光系数达1.8×105L·mol-1·cm-1,在25mL溶液中,钛质量在0～3μg范围内符合比尔定律。显色反应有良好的选择性,方法简单、灵敏,可不经分离直接测定陶瓷原料中钛,结果满意。
In the medium of 0.5mol.l^-1H2SO4 and in the presence of OP,HMPF reacts with titanium IV to form a red complexwith a maximum absorption peak at 536 nm. The apparent molar absorptivity of the complex is 1.8×1051· mol^-1 · cm^-1. Beer＇ s law is obeyed for the concent ration oftitanium in the rang of 0- 3 μg/25ml.The proposed method is sensitive and selective ,which has been applied to determine the titanium in ceramic materials without separation with satisfactory results
