Fe(Ⅱ)(Ⅲ)—EDTA体系研究(Ⅳ)
Study of The Fe(Ⅱ)(Ⅲ)—Edta System(Ⅳ)
摘要
Abstract
This paper deals with the rule of photoreduction of system of Fe(Ⅱ)(Ⅲ)—phen in process of extraction.
It is discovered that in diffused light a remarable photoreduction of Fe3+—phen complex occurs;that when EDTA is added into the system the photoreduetion is prevented,however thereaction in which Fe(Ⅲ)is reduced into Fe(Ⅱ)by NH2OH.HCl is not in-fluenced;and that the determination of iron valence state is not affected when a small amount of reduet(S2O32-)is present.
This method can be applied to the determination of Fevaleuce state in system of Fe(Ⅱ)(Ⅲ)—EDTA.关键词
