摘要
以水杨基荧光酮（ＳＡＦ）－溴代十六烷基三甲铵（ＣＴＭＡＢ）为显色体系，详细考查了测定条件。采用多波长线性回归分光光度法同时测定了Ｗ－Ｍｏ－Ｎｉ／Ａｌ２Ｏ３加氢催化剂中的钨和钼。相对标准偏差小于１．６％，合成样品回收率９４．０％—１０６．４％。测定结果与比色法（分别测定）及Ｘ－射线荧光光谱法相吻合．
Multiwavelength linear regression spectrophotometry has been used to determine wolfram and molybdenum in catlyst simultaneously by using the system of metal ions-SAFMTMAB. The experimental conditions were investigated in detail. The relative standard derivation is less than 1.6%, the experimental results agree with those obtained by XRF.
