摘要
以Ｒ系数消除剩余试剂影响获得配合物纯光谱，借多元线性回归部分校正原理确定试剂平衡浓度，根据配位反应平衡常数不随金属和试剂反应浓度的变化而改变，以不同组成初始输入条件计算机试探获得配合物组成和稳定常数。最后确定了本文试验条件下Ｐｂ－ＸＯ、Ａｌ－ＣＡＳ和Ｚｎ－ＰＡＲ体系配合物组成均为１∶２。
The pure spectrum of the complex is obtained by R factor method to eliminate the absorbance of equilibrium concentration of residual reagent.The reagent concentration is determined by multiple linear regression method.As initial concentrations of metal and reagent are changed,and the stable constant is not changed,complex composition and its constant are acquired by means of trial method,in which the input parameters, m and n,are selected.Then the K value is calculated and the minimum value of the total derivation in K is found.By this method,the composition of complex in systems such as Pb XO,Al CAS and Zn PAR are all to be 1∶2.
