摘　　要：采用微波消解技术,用HNO_3-HCl-HF-H_3BO_3作为消解溶液,在110～100℃下将剩余污泥样品加热约40min,样品溶解后,用电感耦合等离子体-原子发射光谱法(ICP-AES)测定其中的全硫含量。方法的检出限为0.0084μg/mL,回收率为96.9%～105.3%,精密度为0.81%～2.39%。将本方法用于污泥中全硫的日常检测,有利于对剩余污泥作出科学的处理,防止对环境造成污染。Sludge sample was digested with microwave digestion technique in HNO3-HCl-HF-H3BO3 solution heated at 110-100℃ for 40 rain. After the sample was dissolved, the total sulphur was determined by ICP -AES. The detection limit was 0. 0084μg/mL, the recovery was 96.9-105.3% and the precision was 0. 81%-2. 39%. The method can be used for routine analysis of total sulphur in sludge to protect environment from pllution.
