ABSTRACT. Conditions for the on-line immobilization of hexaoxacycloazochrome on the inner hydrophobic surface of a capillary column were selected. The retention of several metals on the column obtained and the influence of various parameters of the flow system on sample dispersion in the capillary column were studied. A procedure for the flow sorption-photometric determination of lead with on-line preconcentration was developed.
