摘要：

The solid monoxime of 2,3-butanedione is a more convenient material than liquid dione for the homogenous generation of DMG,2,3-butanedione dioxime. Determinations of Ni in steels and in pure Ni(II) solutions have shown the optimum pH and order of adding reagents. Gravimetric and/or an EDTA titrimetric finish are possible for a method of reliability within 0.2 mg of Ni in 50–150 mg Ni. The solid has the same character and filterability as that from the 1960 dione method of Salesin and Gordon1. © 1979 Taylor & Francis Group. All rights reserved.
