铅精矿样品高温焙烧后用硝酸、盐酸溶解完全后，经活性炭静态吸附、棉花纸浆过滤、灰化、王水溶解，采用电感耦合等离子体-原子发射光谱法（ICP-AES）测定其中的金含量。该方法的加标回收率为94.23豫~97.13豫，相对标准偏差（RSD）为4.95%，线性范围宽，具有良好的准确性和精密度，测定结果与FAAS（火焰原子吸收光谱法）法吻合。与FAAS法相比较，ICP-AES法具有更宽的线性范围，干扰小，准确度高，快速简便等优点。适合用来测定铅精矿中的金。

The contents of Au in lead concentrates was determined by inductively coupled plasma-atomic emission spectrometry （ICP-AES） by using nitric acid and hydrochloric acid to dissociate, absorbing with particle activated carbon, then filtrating with paper pulp. The standard addition recovery was 94.23%~97.13%, and the relative standard derivation was 4.95%. This method showed wide 1inear-range, good accuracy and precision, the results of determination were in agreement with those of FAAS. Compared with FAAS, ICP-AES had wider linear range, and can determine the contents of Au in lead concentrates quickly and correctly. So this method can use to determine the contents of Au.
