Due to the increasing deterioration of the environment,
European industry is forced to run its business in a manner least
disruptive to the surroundings [1]. A major threat to the environment
constitute such contaminants as heavy metal ions. Their
sources include metal finishing industry, where electrochemical
methods are used. In recent years, there has appeared a trend
towards elimination of certain heavy metal ions in these processes
[2], but this is not always possible due to the lack of alternative
technologies. In this case one can only do the activities eliminating
hazardous chemicals from waste streams and recycle them [3,4]. In
purification of waste waters from metal surface treatment by electrochemical
methods the ion exchange method one is of significant
importance.
