Im. Maksimova et al., SEGMENTED-FLOW ANALYSIS - SORPTION-PHOTOMETRIC DETERMINATION OF LEAD WITH A CAPILLARY COLUMN, Journal of analytical chemistry, 51(4), 1996, pp. 365-368
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 c
apillary column were studied. A procedure for the flow sorption-photom
etric determination of lead with on-line preconcentration was develope
