A membrane optode was developed utilizing the 8-hydroxyquinaldine (HQ) facilitated preconcentration of UO(2)(2+) ions and subsequent colored complex formation of UO(2)(2+) with 4-(2-thiazolylazo)-resorcinol (TAR) in optode matrix. The composition of the membrane optode was optimized by scanning several extractants immobilized

Co(II), Zn(II), Ni(II) and Fe(I) were successfully separated by capillary electrophoresis using pre-capillary and on-capillary complexation with 4-(2-thiazolylazo)resorcinol. The influences of some crucial parameters, including both pre- and on-capillary complexation procedure, were investigated. For on-capillary complexation, the complexing reaction was
