Claims (1)
- Для эффективного и простого восстановления отработанной серной кислоты, удаляемой в большом количестве, например, из кислотной промывочной жидкости или при производстве двуокиси титана сульфатным способом в виде высококонцентрированной серной кислоты, ионы двухвалентного железа в отработанной серной кислоте, содержащей сульфат металла, сначала окисляют в ионы трехвалентного железа, добавляют в такую жидкость соляную кислоту и затем осуществляют экстракцию растворителем.
