Abstract

A procedure is proposed for separating trace amounts of gallium from the macrocomponents Cr, Mo, W, Ni, and Co to determine gallium using inductively coupled plasma atomic emission spectroscopy in alloys based on nickel and iron (precision nickel alloys, alloyed and high-alloyed steel). Sodium fluoride was used as a precipitant. Optimal conditions for the coprecipitation of gallium on the precipitate during separation from the considered macrocomponents were determined. The limit of detection for gallium in separation from the macro quantities of Cr, Mo, W, Ni, and Co was 5 × 10–4 wt %.
