摘　　要：以吹制锌粉、电炉锌粉、合金锌粉和蒸馏锌粉为研究对象,考察了不同锌粉在锑盐净化除钴工艺中锌粉用量、反应时间、反应温度、铜和钴物质的量比、锑和钴物质的量比对除钴效果的影响。结果表明,按铜和钴物质的量比5.0加入硫酸铜、锑和钴物质的量比0.5加入酒石酸锑钾,在反应温度90℃、反应时间90 min、转速300 r/min、锌粉加入量2 g/L条件下,4种锌粉实际除钴率分别为95.73%、96.15%、95.94%和94.87%,除钴效果依次为:电炉锌粉>合金锌粉>吹制锌粉>蒸馏锌粉。Blown zinc powder,electric furnace zinc powder,zinc alloy powder and distilled zinc powder were respectively taken in the test of cobalt removal by arsenic trioxide purification process to investigate influences of several factors on cobalt removal effect,including an adding amount of zinc powder,temperature and time of reaction,a mole ratio of copper to cobalt and a mole ratio of antimony to cobalt.Results show that when copper sulfate is added with copper and cobalt in a mole ratio of 5.0,potassium antimony tartrate is added with antimony and cobalt in a mole ratio of 0.5,a reaction at 90℃for 90 min,with rotation speed of 300 r/min and addition of zinc powder at an amount of 2 g/L,the cobalt removal rates by using 4 different kinds of zinc powder are 95.73%,96.15%,95.94%and 94.87%,respectively,indicating the cobalt removal effect of different powder in the following descending order:electric furnace zinc powder>zinc alloy powder>blown zinc powder>distilled zinc powder.
