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 detecti
## Abstract **BACKGROUND:** Phosphate is one of the main contaminants responsible for the eutrophication of surface waters. In developing countries, algae blooming in lakes have threatened the quality of drinking water due to the lack of proper management of phosphateβcontaining wastewaters from mi
