金矿焙烧工艺金精粉及处理液中汞、砷的测定

Determination of mercury and arsenic in gold concentrate powder and treatment liquor in the roast technology of gold concentration

文中针对金矿焙烧工艺生产中金精粉及尾气、尾液处理液中汞、砷的监测方法进行了研究。试样采用王水分解 ,硫脲 -抗坏血酸溶液还原 ,原子荧光光谱法测定。该方法与化学法及其它仪器法比较 ,具有灵敏度高、重现性好。

The mercury and arsenic contents of gold concentrate powder and treatment liquor of tail gas and tail liquor in the roast technology of gold concentration are determined by fluorscence spectrometry after dissociation with aqua regia and reduction with thiourea ascorbic acid liquor.This method is characterized by higher sensibility,better reproducibility and speedy analysis compared to chemical method and other instrumentations.
