Several materials were tested for their usefulness as supports to immobilize 8-quinolinol through an azo bonding to prepare clean adsorbents for the preconcentration of trace metals in water. Satisfactory results were obtained with CAPCELL-NH_2 (siliconecoated silica gel with alkyl amino groups), and with SEPABEADS (polyvinyl polymer with alkyl amino groups). The adsorbents synthesized from them are clean and can be used for the concentration of metals prior to determination by GFAAS or ICP-MS. Six metals (Cd, Cu, Fe, Ni, Pb, and Zn) in the standard seawater sample, NASS-3,were determined by GFAAS after enrichment with 8-quinolinol bonded SEPABEADS. The results were in good agreement with the certified concentrations.
