概要

• 論文の詳細を見る

• In the distillation without silver, most of the selenium and tellurium in crude sulfur appeared in the distillate. However, these impurities were removed by distillation using a column which was filled with silver and heated at 600–700 °C. The removal of them in the process was confirmed in a tracer experiment.
