Аннотация
В работе приведены результаты экспериментальных исследований по определению возможности повышения фотокаталитической активности диоксида титана за счет применения оксида вольфрама (VI), путем тестирования разложения родамина Б как органического загрязнителя в водных растворах под действием УФ-излучения, в том числе в видимом спектре. В качестве фотокатализаторов использовался промышленный диоксид титана рутильной модификации и триоксид вольфрама, полученный методом биологического синтеза за счет использования жизнедеятельности тионовых бактерий (Thiobacillus ferrooxidans). Установлено, что концентрация красителя в растворе со смесью TiO2 и WO3 в соотношении 1 : 1 под действием естественного солнечного излучения снизилась на 85 % после 28 дней исследования в сравнении с 30 % и 42 % для растворов с чистыми WO3 и TiO2 соответственно.
