【摘要】 分别将系列Fe(Ⅵ)碱性溶液加热到65℃、75℃、85℃、95℃,用分光光度法跟踪热溶液中发生的反应.在热溶液中Fe(Ⅵ)分解生成Fe(OH)3,同时存在着Fe(Ⅵ)向Fe(Ⅳ)的转化反应.新生成的Fe(Ⅳ)溶液2 h即达最高浓度,并且在85℃以下能稳定存在.更多还原

【Abstract】 A series of alkaline ferrate(Ⅵ) solution are heated up to 65 ℃,75 ℃,85 ℃,95 ℃ respectively,and the reactions in the solution are traced by visible spectrophotometry.The conversion reactions of Fe(Ⅵ) to Fe(Ⅳ) coexist in the hot solution with the reaction that Fe(Ⅵ) decompose to Fe(OH)3.The product ferrate(Ⅳ) solution could reach its maximum concentration after 2 h,and could exist stably under 85 ℃.更多还原
