Abstract
Six plant pigments separated by paper chromatography have been measured by photoacoustic spectroscopy (PAS). Their PA spectra are compared with the corresponding absorption spectra, which indicate that PAS is a convenient and effective method for identifying plant pigment. The sorts of marine algae are numerous and pigments in marine algae have certain characteristics. The PA spectra of green, red and brown algae have been reported. Pigment characteristics in these algae are identified by their second derivative PA spectra.
