Description
Известны способы очистки серы от селена путем обработки ее в расплавленном состо нии окислител ми, например азотной кислотоп, персульфатом кали , перхлоратом натри , в результате которой селен , окисл сь, переходит в раствор, а сера отгон етс .Methods are known for purifying sulfur from selenium by treating it in a molten state with oxidizing agents, for example, nitric acid, potassium persulfate, sodium perchlorate, as a result of which selenium, oxidized, goes into solution, and sulfur is distilled off.
Преимуществом предлагаемого способа очистки серы от селена вл етс то, что в качестве окислител селена примен етс более дешевый , менее агрессивный реагент-хлорна известь (при концентрации 20-30г/л), что снижает содержание селена в сере до 0,01%.The advantage of the proposed method of purification of sulfur from selenium is that cheaper, less aggressive reagent-bleach (at a concentration of 20-30 g / l) is used as an oxidant of selenium, which reduces the content of selenium in sulfur to 0.01%.
Предлагаемый способ отличаетс от известных тем, что, с целью удешевлени очистки и использовани менее коррозионно стойкой аппаратуры , окисление селена ведут суспензией хлорной извести и отмывают от серы в промывных аштаратах, примен емых при очистке серы от мышь ка.The proposed method differs from those known in that, in order to reduce the cost of cleaning and use less corrosion-resistant equipment, selenium oxidation is carried out with a suspension of bleach and washed from sulfur in washing ashtrats used in cleaning sulfur from mouse.
Обработка серы хлорной известью дл окислени и последующего отделени примесей селена осуществл етс при 130-140°.Sulfur treatment with bleach for oxidation and subsequent separation of selenium impurities is carried out at 130-140 °.
Предмет изобретени Subject invention
Способ очистки серы от селена путем окислени селена при температуре выше точки плавлени серы и перевода его в растворимые соединени с последующей отгонкой серы, отличающийс тем, что, с целью удешевлени очистки и использовани менее коррозион но стойкой аппаратуры , окисление селена ведут суспензией хлорной извести и отмывают от серы в промывных аппаратах, примен емых при очистке серы от мышь ка.The method of purification of sulfur from selenium by oxidizing selenium at a temperature above the melting point of sulfur and converting it into soluble compounds followed by distilling off sulfur, characterized in that, in order to reduce the cost of purification and use less corrosive equipment, the oxidation of selenium is carried out with a suspension of bleach and washed from sulfur in the washers used in the cleaning of sulfur from the mouse.
