摘要
测定了纸色谱分离的极为微量的六种植物色素的光声光谱 ,并与相应色谱斑点溶出物的吸收光谱进行对照 ,表明光声光谱对植物色素的鉴定简便有效。海藻类别众多 ,所含色素体系各有特征 ,本文报道了绿藻、红藻和褐藻的光声光谱 ,并用导数光谱法明确了这些藻类的色素分布特征。
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.
