变色酸(XK)、二安替吡啉甲烷(дAM)是测定钛的两种重要试剂。近年来ганаго等研究了钛-二安替吡啉甲烷-溴代邻苯三酚红及钛-二安替吡啉甲烷-变色酸的形式分光光度法测定钛。我们对后者进行了研究,经试验发现显色液中有白色针状结晶析出。我们加入了乙醇防止了沉淀析出并对多种离子进行了干扰试验。实验证明本法是一个高选择性、精密度较好的快速分析法。
Chromochromic acid (XK), diantipyrylmethane (дAM) are two important reagents for the determination of titanium. In recent years, ганаго such as titanium - two antipyrine methane - Brominated pyrogallol red and titanium - two antipyrine methane - chromotropic acid spectrophotometric method for the determination of titanium. We conducted a study of the latter, the test found that there is a white needle crystallization of color liquid precipitation. We added ethanol to prevent the precipitation and precipitation on a variety of ions interference test. Experiments show that this method is a high selectivity and rapid precision analysis method.
