采用碳酸钠-氧化锌混合物半熔,将试样中的硫全部转化成可溶性硫酸盐,然后用硫酸钡重量法测定铅锑精矿中硫含量.用本法测定硫量,方法精密度高,准确度好,结果稳定可靠,硫的测定范围为15.00%~30.00%;方法精密度(RSD值为)为0.314%~0.550%,回收率在99.24%~101.78%之间,完全满足铅锑精矿中硫量的测定要求.
採用碳痠鈉-氧化鋅混閤物半鎔,將試樣中的硫全部轉化成可溶性硫痠鹽,然後用硫痠鋇重量法測定鉛銻精礦中硫含量.用本法測定硫量,方法精密度高,準確度好,結果穩定可靠,硫的測定範圍為15.00%~30.00%;方法精密度(RSD值為)為0.314%~0.550%,迴收率在99.24%~101.78%之間,完全滿足鉛銻精礦中硫量的測定要求.
