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。
鉛精礦樣品高溫焙燒後用硝痠、鹽痠溶解完全後,經活性炭靜態吸附、棉花紙漿過濾、灰化、王水溶解,採用電感耦閤等離子體-原子髮射光譜法(ICP-AES)測定其中的金含量。該方法的加標迴收率為94.23豫~97.13豫,相對標準偏差(RSD)為4.95%,線性範圍寬,具有良好的準確性和精密度,測定結果與FAAS(火燄原子吸收光譜法)法吻閤。與FAAS法相比較,ICP-AES法具有更寬的線性範圍,榦擾小,準確度高,快速簡便等優點。適閤用來測定鉛精礦中的金。

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.
