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。
A method for direct determination of SO4^2- 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 SO4^2- 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 SO4^2- in standard reference water samples with satisfactory results.
