METHOD AND APPARATUS FOR THE DECONTAMINATION OF PRODUCTS CONTAINING HEAVY METAL

摘要

According to the invention, by using the electro-kinetic principle for a method for the cleaning of materials contaminated with heavy metals, and whereby use is made of an apparatus comprising two charge-selective ion-exchange membranes with different charges combined with an inner and an outer electrolyte solution chamber which are separated from the membranes which serve a blocking function, a surprisingly good degree of utilization is achieved, particularly in relation to the current consumption, and at the same time the precipitation of the heavy metals is so effective that they can be reused. There is hereby achieved a hitherto-unknown degree of profitableness compared with known methods of cleaning.
