摘　　要：提出了用离子选择电极电位法测定硫酸盐的新方法.在最佳条件下,电极电位与硫酸盐浓度在1×10-5～1×10-2mol/L之间有良好线性关系,检测下限为6.3×10-6mol/L.该方法简便准确,已用于水中硫酸盐测定,结果满意.This paper presents a new method to determine sulphte with ion selectivity electrode. Under the optimum condition, good linearity between the potential and sulphate concentration is drawn in the range of 1×10^-5～1×10^-2moL/L . The detection limit is 6.3×10^-6moL/L. The method is applied for determining sulphate in water with good result.
