锑矿中微量砷的测定一般采用蒸馏或萃取分离富集砷,以钼蓝法比色。但蒸馏-钼蓝法、砷化氢-铜试剂银法对高锑矿中微量砷的测定,回收率都不理想,而萃取法劳动强度大。俞穆清等对巯基棉富集分离技术作了大量的研究工作。可被巯基棉定量吸附的元素多达16种,在环境污染及水质分析方面应用广泛。但对矿石中,特别是锑含量高(含20～60%锑)的精矿及高锑浸出液中微量砷的测定尚未见报导。本文利用巯基棉对高锑矿石及锑浸出液中微量
Determination of trace arsenic in antimony ore commonly used distillation or extraction enrichment arsenic, molybdenum blue colorimetric method. But distillation - molybdenum blue method, arsine - copper reagent silver method for the determination of trace arsenic in high antimony ore, the recovery rate is not ideal, and the extraction method of labor-intensive. Yu Muqing and other enrichment of thiamin cotton separation technology made a lot of research work. Up to 16 elements can be quantitatively adsorbed by sulfhydryl cotton, widely used in environmental pollution and water quality analysis. However, the determination of trace arsenic in ores, especially in concentrates with high antimony content (20-60% antimony) and in high antimony leaching solutions, has not been reported yet. In this paper, mercapto cotton on the antimony and antimony leaching solution trace
