摘要： 研究了高锰酸钠对水中苯胺的去除作用·实验结果表明,随着高锰酸钠投加量的增加,水中苯胺的去除率增加,在苯胺初始质量浓度为10mg/L,温度为18℃,pH值为6 8,反应时间为30min的条件下,高锰酸钠质量浓度为30mg/L时,苯胺的去除率达92 12%·水样的pH值对苯胺去除效果有较大影响,在强酸性及强碱性条件下苯胺去除效果高于中性条件,pH值为3时,苯胺去除率为97 55%;pH值为11时,苯胺去除率为96 33%·升高温度或延长反应时间对苯胺的去除均有正的影响·苯胺是通过高锰酸根和新生态的氧将其氧化成苯醌而去除的·

Abstract: Eliminating aniline in water was investigated by sodium permanganate. It is showed that with the increase of sodium permanganate, aniline eliminating rate increases. Aniline eliminating rate reaches 92.12% by the condition of aniline concentration lO mg/L, temperature 18°C ,pH 6.8, reaction time 30 min and sodium permanganate 30 mg/L. The pH value of water sample plays a role on aniline elimination. The effect of removing aniline in alid or alkaline solutions is more significant than in neutral water. The aniline eliminating rate is 97.55% at pH value 3 and 96.33% at pH value 11. Increasing the temperature or the reaction time has good effects on removing aniline. By the cooperation of permanganate and the formed oxygen, aniline is oxidated into guinone and removed.
