摘　　要：建立用系数倍率双波长法同时测定钢样中铝和铜含量的方法。在p H6.0的盐酸和六次甲基四胺缓冲溶液中,Cu2+和Al3+与铬天青S(CAS)和十六烷基三甲基溴化铵(CTMAB)发生高灵敏的显色反应,形成三元胶束络合物。根据实验得到铝和铜的一元线性回归方程,铝的回归方程为A=0.004C+1.121;铜的回归方程为A=0.016C+1.018。A rapid, inexpensive dual ultraviolet wavelength spectrophotometry was established for the de termination of aluminum and copper in steel sample simultaneously. In the conditions that pH of the amor- tize liquid composed with HCl- C6 H12N4 is 6.0 , AP＋ and Cu2＋ arise chemistry reaction with CAS when CTMAB exist in the system . he linear regression equation of aluminum was A=0. 004C＋1. 121; The lin- ear regression equation of copper was A=0. 016C＋1. 018.
