Abstract:
A new technique has been researched on the feasibility and regularity for removing impurities from rude selenium by vacuum distillation in theory analysis. The influence of distillation temperature and time on the effect of purifying selenium is investigated by diminutive experiments. The optimal technical condition is achieved as following： distillation temperature is 483K and distillation time is 20 min. Results show that the content of selenium is more than 99%.[著者文摘]
