Abstract

The extraction behavior of bismuth(III) was studied with N-n-octylaniline as a function of parameters viz. concentration of mineral acid, reagent, eluents and elution time. A selective, sensitive, less expensive and more precise method has been developed for the extraction chromatographic separation of bismuth(III) and its separation from several metal ions with N-n-octylaniline (liquid anion exchanger) as a stationary phase on silica as solid support. The quantitative extraction of bismuth(III) was found at 0.087 mol/L N-n-octylaniline and 0.7 mol/L hydrochloric acid media. The extracted bismuth(III) was eluted from the column with acetate buffer and analyzed spectrophotometrically with potassium iodide method. The proposed method is free from interferences from a large number of cations and anions. The method was applied for separation of bismuth(III) from binary mixtures with lead(II), copper(II) and manganese(II). The method was also extended for separation of bismuth(III) from synthetic alloy mixtures. The log-log plot of N-n-octylaniline concentration versus the distribution coefficient indicates that the probable extracted species is [(RR′NH 2 + )2BiCl 5 2− ](org).
