Abstract

A chromatographic method has been established for the determination of trace amounts of cobalt by preconcentration on Amberlite XAD-16 resin as cobalt/4-(2-Thiazolylazo) resorcinol (TAR) complexes. The conditions (e.g. pH, resin amounts, matrix ions) affecting the recovery of cobalt from aqueous solution were studied. The method has been employed for the determination of cobalt in natural water samples.
