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 conditio ns (e.g. pH, resin amounts, matrix ions) affecting the recovery of cob alt from aqueous solution were studied. The method has been employed f or the determination of cobalt in natural water samples.
