醋酸纤维素为母体的稀土离子选择电极,制备容易,使用方便,可以测定混合稀土,电极的线性范围为1.2×10~(-1)～1×10~(-5)mol/L,适宜的pH范围较宽,测定结果令人满意。
The cellulose acetate is the parent rare earth ion selective electrode, which has the advantages of easy preparation and convenient use. The rare earth ion selective electrode can be used to determine the linear range of the electrode from 1.2 × 10-1 to 1 × 10-5 mol / L. A wide range of pH, the determination of satisfactory results.
