摘要： Provided is a method for preparing high-purity elemental phosphorus capable of simultaneously reducing both arsenic and antimony from crude white phosphorus containing a great amount of arsenic and antimony as impurities. Provided is a method for preparing high-purity elemental phosphorus, the method including bringing liquid crude white phosphorus into contact with an iodic acid-containing compound selected from iodic acid and iodates in an aqueous solvent in the presence of a chelating agent, wherein the chelating agent is selected from polyvalent carboxylic acids, polyvalent carboxylates, phosphonic acid and phosphonates.
摘要翻译： 本发明提供一种能够同时从含有大量砷和锑作为杂质的粗白磷中同时还原砷和锑的高纯度元素磷的方法。 本发明提供一种制备高纯度元素磷的方法，其特征在于，在螯合剂的存在下，在含水溶剂中使液态粗白磷与选自碘酸和碘酸的碘酸化合物接触， 试剂选自多价羧酸，多价羧酸酯，膦酸和膦酸酯。
