Abstract Dipicolinic acid (DPA), a constituent of bacterial spores, complexes with meso-tetra(4-sulfonatophenyl)porphine (TPPS), tetra(4-aminophenyl) porphyrin (NH 2 –TPP), monosulfonate tetraphenyl porphyrin (TPPS 1 ), and meso-tetra(4-carboxyphenyl)porphine (CTPP 4 ) resulting in new absorbance peaks in the visible spectra of the porphyrins at 419, 470, 441, and 415 nm, respectively, with the intensity of these peaks showing linear dependence on DPA concentration. DPA can be detected at… CONTINUE READING
