   <abstract xml:lang="ru">
    <p>В работе проведено описание спектров поглощения ацетонового экстракта микроводоросли Arthrospira (Spirulina) platensis математическими моделями каротиноидов и хлорофиллов в области от 400 до 700 нм. Полученные значения концентрации пигментов хорошо согласуются со стандартными методами. Модель спектра поглощения ацетонового экстракта A. platensis может быть использована для определения концентрации хлорофилла а и каротиноидов без применения методов хроматографии. Показано отсутствие вклада хлорофилла b в суммарный спектр поглощения. Реализован метод математического разделения спектра поглощения ацетонового экстракта в программе Microsoft Excel. Вычисления, выполняющие приближения концентраций пигментов путем минимизации суммы квадратов отклонений между истинным спектром поглощения и его математической моделью, выполнены при помощи табличного процессора с использованием инструмента поиска решения.</p>

    <p>We have described the absorption spectra of acetone extract of the microalga Arthrospira (Spirulina) platensis by mathematical models of carotenoids and chlorophylls in the range from 400 to &#13;
700 nm. The obtained values of pigment concentrations agree well with standard methods. A model of the absorption spectrum of acetone extract of A. platensis can be used to determine the concentration of chlorophyll a and carotenoids. The absence of chlorophyll b contribution to the total absorption spectrum was shown. The method of mathematical separation of acetone extract absorption spectrum in Microsoft Excel program was implemented. Calculations performing approximations of pigment concentrations by minimizing the sum of squares of deviations between the true absorption spectrum and its mathematical model have been performed using the spreadsheet processor with the help of the solution search tool.</p>
