Abstract: | Summary A liquid chromatographic procedure for separating nickel and zinc has been developed. Xylenol orange, which is one of the
sensitive and commercially available color-forming agents, was used as a component of the mobile phase. The two ions could
be separated on weak anion-exchange gels within 10 min. The procedure was suitable for the determination of nickel and zinc
in relatively pure solutions with fairly high sensitivity. The described liquid chromatographic analysis would be also potentially
applicable for any aqueous sample containing trace levels of metal cations at 1–10 ppm. |
