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.
