Abstract

Рассматривается способ регенерации рассола, который включает смешивание рассола, содержащего тиоцианаты, с окислителем; и обеспечение времени, достаточного для того, чтобы окислитель окислил по меньшей мере часть тиоцианатов. Другие способы могут также включать определение количества неокисленных тиоцианатов после обработки окислителем.
