摘要:

The dissociation constants of 4- (4,5 -dimethyl -2-thiazolylazo) resorcinol (DMTAR) and formation constant of its complexes with Cu (II) were measured spectrophotometrically. The utility of DMTAR as the metallochromic indicator for Cu (II) in EDTA titrations is comparable to 4 - (2 -thiazolylazo) resorcinol (TAR).
