Аннотация

В статье представлены результаты исследования сенсорных характеристик жидкокристаллических слоёв фталоцианина кобальта CoPc-py в широком интервале концентраций аммиака. Показана высокая чувствительность плёнок к аммиаку вплоть до концентраций в 50 раз ниже ПДК, хорошая воспроизводимость сенсорного отклика, низкая инерционность отклика, линейный диапазон зависимости аналитический сигнал/концентрации аммиака составляет 0,1–20 ppm. Впервые изучена селективность детекции аммиака в присутствии углекислого газа и водорода. Установлено, что при нормативных концентрациях СО2 в помещении (до 2000 ppm) и при 10000 ppm водорода сенсорный отклик на аммиак изменялся в пределах статистической погрешности. Статья публикуется по результатам проведения научно-исследовательской работы, проводимой в рамках конкурса грантов на выполнение научно-исследовательских работ научно-педагогическими работниками СПбГАСУ в 2022 году.
