Dichlorohydantoin and dibromohydantoin as new oxidimetric titrants in non-aqueous media.

Two new oxidimetric titrants, dichlorohydantoin and dibromohydantoin are introduced for use in acetic acid medium, and have been applied to direct potentiometric titration of AS(III), Sb(III), Sn(II), Fe(II), Tl(I), Fe(CN)(6)(4-), I(-), SCN(-), hydrazine, phenylhydrazine, semicarbazide, hydroquinone, oxine and Reinecke's salt, in aqueous acetic acid medium.
