摘要
在Fe、Ti共存时,邻菲啰啉作Fe的显色剂,邻苯二酚紫、盐酸羟胺和溴化十六烷基三甲基铵与Ti形成四元络合物。在此混合显色体系中,分别在490nm和720nm波长测定Fe和Ti互不干扰。方法用于水系沉积物和岩石中Fe和Ti的同时测定,取得了满意的结果。
0-Phenanthroline is used as colour reagent for Fe(Ⅱ), and pyrocatechol violet, NH2OH???HC1 and CTMAB are used to form a quaternary complex with Ti(Ⅳ). In a mixed colour system, Fe and Ti can be determined by spectropho-tometry at 490nm and 720nm respectively. The method has been applied to simultaneous determination of Fe and Ti in river sediment and rock with satisfactory results.
