| 摘 要： | 建立了盐酸直接酸化地表水和地下水,电感耦合等离子体发射光谱法测定硫酸根含量的方法。方法检出限为0.031 mg/L。在硫波长182.0 nm处测定的线性范围为0.03~100 mg/L,182.6 nm处的线性范围为100~700 mg/L。对实际水样进行连续12次测定,方法精密度(RSD)为0.76%。经国家水标准物质验证,结果与标准值相符。方法快速、准确。

| Abstract: | A method for direct determination of SO2-4 in acidized surface water and underground water by inductively conpled plasma-atomic emission spectrometry(ICP-AES) was described.The detection limit of the method for SO2-4 was 0.3 mg/L with dynamic linear range of 0.03～100 mg/L for 182.0 nm determination line and 100～700 mg/L for 182.6 nm line.The analytical precision for the actual samples was 0.76%RSD(n=12).The method has been applied to the determination of SO2-4 in standard reference water samples with satisfactory results. |
