摘　　要：利用微波消解技术处理样品,使饮用水中硼在碱性溶液中呈稳定状态,用电感耦合等离子体质谱法(ICP-MS),采用在线加入内标,可直接测定水中的微量硼。该方法具有较高的灵敏度和精密度,相对标准偏差(S)为2.66%,回收率在99.18%～102.33%之间,该方法简单、快速,结果较为满意。The samples were treated by the microwave digestion technology to keep boron in drinking water stable in an alkaline solution. The inductively coupled plasma atomic emission spectrometry method （ICP-AES） was used to directly determine trace boron in drinking water, with the online addition of internal standards. Featured by relatively high accuracy and precision, the method was simple and rapid, and the results were satisfactory, with the RSD（S） being 2.66% and the recoveries ranging from 99.18% to 102.33%.
