摘　　要：利用工业品CaCl2和Na2CO3生成的CaCO3与工业品FeCl3.6H2O的协同作用,制得除铅效率高而成本低的碱性蚀刻废液除铅剂。利用二次回归正交设计得到脱铅率的二元二次方程,最佳配比是CaCl210.66 g/L(相应的Na2CO310.18 g/L),FeCl3.6H2O 1.38 g/L。绘出了脱铅率的等高线图,为设计除铅剂的配比提供了直观有效的方法。A high efficient and low cost reagent for removing lead of the alkaline waste etching liquid was prepared by using a mixed nascent calcium carbonate-ferric hydroxide. A quadraic removing lead rate equmion was derived by regression orthogonal design. A optimal mixing proportion of removing lead was： CaCl2 10.66 g/L（Na2CO3 10.18 g/L）,FeCl3·6H2O 1.38 g/L. Accordingly,a practical removing lead rate contour map is given for reference. A direct and effective method is put forward to design for mixing proportion of removing lead.
