The spectrophotometric properties of porphyrins are altered upon
interaction with nucleic acids, proteins, and amino acids. TPPS
immobilized as a monolayer onto a cellulose film exhibits an
absorbance peak in the Soret region. The interaction of the
porphyrin with the follwing amino acids arginine, glycine,
histidine and serine induces blue shifts in the Soret that enables
us to quantify and identify these amino acids in the nM scale. The
interaction of PCP with the following porphyrins and
metaloporphyrins TPPS, Zn-TPPS, TPPS1, C1TPP, C4TPP, Cu-C4TPP in
solution induces a red shift in the Soret spectrum that enables us
to quantify PCP in concentrations less than the MCL recommended by
EPA. The interaction of the TPPS1 immobilized as a monolayer on a
Kimwipe(r) tissue with PCP induces a red shift in the Soret
spectrum that enables us to detect PCP as low as 0.5ppb. The
Photocatalytic degradation of PCP by the above porphyrins in
solution and the immobilized TPPSCl as catalysts in pH7 buffer was
achieved using fluorescence light. It is believed that singlet
oxygen 1O2 is the major oxidant species that was photosensitized,
and accomplish the mineralization of PCP to CO2 and HCl.
