摘要：
The purpose of our study is to remove heavy metals from wastewater through the use of crude clay. The adsorption kinetics of Zn (II) on the clay is of a maximum value with a yield of the order of 58.07% after 30 minutes of contact, and the pseudo-second order model is the most suitable to describe the adsorption kinetics. Wastewater treatment tests perform more than satisfactorily with a three-day contact time. Regarding the removal efficiency of Cu (II) and Pb (II) it is over 31%. © 2022, Politechnica University of Bucharest. All rights reserved.
