Модификация бентонита осуществлялась насыщением раствором нитрата лантана (0.7 мг/см³), с последующим промыванием и сушкой. Для анализа сорбционных свойств использовались УФ-спектрофотометрия (λ=361 нм) и расчет статической сорбционной емкости. Кинетика адсорбции моделировалась уравнениями псевдо-первого и псевдо-второго порядка.
Модификация бентонита лантаном значительно улучшила сорбционную способность (до 0.3579 мкмоль/г) и скорость адсорбции. Кинетический анализ показал, что модель псевдо-второго порядка лучше описывает процесс адсорбции как для исходного, так и для модифицированного образцов. Хемосорбционный механизм подтверждается высокой степенью адекватности модели (R²> 0.9999). Природный бентонит продемонстрировал более низкую сорбционную емкость (0.1159 мкмоль/г) и скорость сорбции.
Цель работы: исследование кинетики сорбции витамина B12 на природном и модифицированном лантаном бентоните, а также анализ механизма адсорбции. Модификация бентонита ионами лантана значительно повышает эффективность сорбции витамина B12. Усовершенствованный сорбент перспективен для применения в биомедицинских и экологических процессах благодаря высокой селективности и сорбционной емкости.
