【摘要】 以水杨基荧光酮为显色剂，确定了光度分析法同时测定钼、钨、锡、锑四组份的最佳条件。并采用迭代目标转换因子分析光度法，对地质样品中上述四组份进行了测定，测定结果的相对误差一般小于１０％ 。对浓度矩阵的实验设计、主因子数的确定、干扰及消除等问题进行了讨论更多还原

【Abstract】 Iterative target trasformation factor analysis (ITTFA) has been applied to the simultaneous determination of molybdemum wolfram,tin and stibium in geological samples with salicylfluorone hexadecyltrimethylammonium bromide (SAF CTMAB).The relative error is less than±10%.The construction of standard matrix,the definition of principal factor number,interference and elimination have been discussed.更多还原
