| 摘 要： | 本文对利用电感耦合等离子体发射光谱法（ICP--AES）测定锅炉水中硫、磷含量的方法进行了探讨。对射频功率、泵速、雾化器流量和观察高度等仪器条件进行了优化选择，考察了检测方法的准确度和精密度。硫、磷的方法检出限分别为0．035mg／L、0．089mg／L，相对标准偏差（RSD，n=9）为0．52％～0．69％。

| Abstract: | The inductively coupled plasma atomic emission spectrometry （ICP-AES） method was developed for determination of S, P in boiler water. The instrument operating parameters were optimized such as power, nebulizer flow, pump rate, observation height. The detection accuracy and precision of the method were investigated. The detection limit of the method was 0.035 mg / L for SO4 2-, 0.089rag/L for PO4 3-. The precision of the method RSD n=9 were between 0.32%-0.69%. |
