A highly insoluble metalloporphyrin polymeric material was used as sorbent for the solid‐phase extraction of phenolic compounds. Substantial quantities of phenols (40 to 60 mg/g polymer) were absorbed from aqueous solution comparing satisfactorily with other extraction methods. The polymeric phase presented similar K SPE values for the hydrophobic compounds tested such as p ‐chlorophenol, BPA, p ‐nitrophenol, and a significant lower value for the more hydrophilic p ‐aminophenol and cresol. Several metallic complexes of protoporphyrin IX (Co 2+ , Cu 2+ , Ni 2+ , Zn 2+ , and Fe 3+ ) have been tested. The analytes were extracted with high recoveries at acid and neutral pH values, whereas at pH 10 low recoveries were obtained. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 81: 3038–3043, 2001
