✦ Synopsis

Resins synthesized from qumohn-b-01 and resorcmol or hydroqmnone, with furfuraldehyde, formaldehyde or benzaldehyde as cross-hnkmg agent, were used for the preconcentrafion of nanogram amounts of lead The rate of exchange and activation energy of lead exchange were calculated Column separations of lead-copper and lead-zmc did not show any cross-contarnmation A contmuous-flow manifold usmg resin rmcrocolumns was developed for the preconcentration and determmation of lead
