Abstract
The metallic ions have an important toxic potential on environment. This makes necessary the treatment of industrial wastewaters before dumping them to sewers or natural receptors. Our research was focused on testing several materials (bio-sorbents) of ligno-cellulosic type (cellolignine and carbon of vegetal origin).
