Spectrophotometric detection of pentachlorophenol (PCP) in water using immobilized and water-soluble porphyrins

These results suggest the potential for development of spectrophotometric chemosensor for PCP residues in water with detection limits less than US EPA maximum contaminate level (MCL) of 1 ppb. The immobilized TPPS1 on the Kimwipe® will make it possible to develop a wiping sensors to monitor the PCP or other pesticides residues on the vegetables or wood products.
