摘要
简述了真空蒸馏原理,通过计算说明了铅等杂质与镉在真空状态下的有效分离,并就常压与真空状态下镉的沸腾温度进行比较,体现真空蒸馏节能降耗,同时简述了真空蒸馏的操作实践。
This paper describes the principle of vacuum distillation of bullion ca dmium,illustrates the efficient se p-aration lead impurity etc.from cadm ium in state of vacuum.compares the b oilling temperature at normal press ure and in the state of vacuum,indicates the energy saving in the process of vacuu m distillation,at the same time desc ribes the practice of vacuum distillation.
