title: EVALUATION OF THE PIGMENT COMPOSITION OF MICROALGAE PORPHYRIDIUM PURPUREUM ACCORDING TO THE TRUE ABSORPTION SPECTRUM OF THE CULTURE USING A SPREADSHEET PROCESSOR
abstract: The paper describes a method for mathematical separation of the absorption spectrum of the culture of the red seaweed Porphyridium purpureum using a spreadsheet processor - the Microsoft Excel program. This method represents the analysis and separation of overlapping pigment bands in the native absorption spectrum of a culture. The culture spectra were recorded on a spectrophotometer near and at a distance from the entrance window of the integrating sphere. The true absorption spectrum is calcul
