Spectrophotometric determination of cobalt in pepperbush leaves and coal fly ashes using 2-(2-benzothiazolylazo)-5-dimethylaminobenzoic acid
Abstract
An extraction-spectrophotometric method has been developed for the determination of cobalt using 2-(2-benzothiazolylazo)-5-dimethylaminobenzoic acid (BTAMB). The method has been applied to the determination of cobalt in pepperbush leaves and coal fly ashes with good precision and accuracy.
