Artigo:

Industrial wastewaters are often contaminated by heavy metals, which can be very hazardous even at low concentrations. Several techniques for removing heavy metal ions have been used over the last century but their cost has usually been high, leading to the study of adsorption as a very promising, low-cost and simple process for metal removal in the last years. This study aims to investigate adsorption of mixed Cu
