Claims (1)
- Предлагается полиуретановый жидкостной абсорбент в форме частиц, предпочтительно содержащий микросферы, а также способ его получения. Абсорбент может быть использован для очистки от пролитых жидкостей, начиная от подвижных жидкостей, таких, как керосин, кончая вязкими жидкостями, такими, как сырая нефть. Абсорбент и абсорбированная жидкость легко отделяются друг от друга путем центрифугирования, что обеспечивает получение регенерированных жидкости и абсорбента для повторного использования.
