Abstract

Because of the increasingly importance of industrial and agricultural activities, many pollutants reach aquifers that deplete groundwater quality and rivers with organic and inorganic pollutants such as heavy metals. These latter are huge nuisance to public health and cause serious problems because of their stability and low biodegradability by natural processes.In this study, we tried to develop an abundant raw material from the sand dunes of M'zar (Agadir region) by cleansing them through adsorption wastewater containing heavy metals (Pb, Cd, Cr and Zn). The results are comparable to other media such as kaolinite, Cotton fibers and sawdust.

Highlights

Nowadays the problem of heavy metals from wastewater has become increasingly worrisome
This study’s main object is the promotion of a abundant raw material in Morocco’s sand dunes of M’zar (Agadir region). This will cleanse them through adsorption wastewater containing heavy metals such as cd, Pb, Cr and Zn
The metal cations were prepared from the following salts: for lead Pb(NO3)2, Cd(NO3)2 were used.4H2O for cadmium, CrCl3.6H2O for chromium and ZnCl2 for zinc

Summary

Introduction

Nowadays the problem of heavy metals from wastewater has become increasingly worrisome. A common feature of industrial effluents is the fact that they almost always contain harmful heavy metals [1, 2]. The maximun level of these metals must be limited. Several treatment methods have been used to eliminate these pollutants [3]. This study’s main object is the promotion of a abundant raw material in Morocco’s sand dunes of M’zar (Agadir region). This will cleanse them through adsorption wastewater containing heavy metals such as cd, Pb, Cr and Zn
