✦ Synopsis
A chemically modified sorbent was evaluated as a preconcentration substrate in solid-phase extraction of phenol and chlorophenols. Tetrakis(p-carboxyphenyl) porphyrin (H 2 TCPP) was chemically bonded to porous polymeric XAD resins by ketone linkage. Breakthrough volumes, recovery values, and detection limits were determined. The synthesized sorbent showed higher recoveries in tap water than commercially available sorbents such as XAD-2 and XAD-4.
