摘　　要：对超细三氧化二锑水萃液电导率的测定条件进行了研究,提出了超细三氧化二锑水萃液电导率测定方法为:料液比10/100,振荡器振荡30min,静置10min使样品分层,电导电极棒置于澄清液中部,5min后读数,测定电导率。测定结果标准偏差0.028,检出限0.084g·mL-1,表明该方法准确可靠。The determination conditions for conductivity of water extract from electronic-grade of antimony oxide were studied. The methods were： 10/100 for solid to liquid, oscillation for 30mins, standing for 10mins, electrodes were placed in the middle of clear supernatant; read for results after 5rains, The deviation between the results with the standard was 0.028, and the detection limit was 0.084g/ mL, showed the methods was accurate and reliable.
