Abstract

Oils shales are the largest energy resource in the world and are widely used in the development of industrial fuel and petroleum activities. Oil shale is one of the important mineral resources in Morocco and it has a large reserve, the most important of which is of Timahdit, Tarfaya, and Tangier. Nowadays, the increasing concentration of toxic organic species (Antibiotics, Colorants) in soils and domestic, agricultural, and industrial wastewater has become a major environmental concern. for this reason, we have focused on the interactions of raw oil shale deposits with toxic organic species as part of an additional valuation of national energy resources. Our work is focused on the contribution of organic matter on antibiotic retention, as well as the role of hydrophobic interactions on the molecules-mineral surfaces. The results of the characterizations show the possible contribution of raw oil shales in the accumulation of organic pollutants in soil and water. Thermally treated oil shell powders can be good mineral sorbents for environmental cleaning.

Summary

Introduction

Rapid industrialization and urbanization have resulted in the deterioration of the quality of water, air, and soil. Industrial, agricultural, or urban human activities produce polluting substances of different kinds: physical, organic and microbiological, or chemical. This pollution can be permanent (domestic discharges), periodic or accidental [1]. Natural waters are contaminated with heavy metals, dyes, and pharmaceuticals from mining, industrial waste, and discharges [2]. Discharges from pharmaceutical industries are considered as pollutants that influence the ecological system and cause human and animal health problems [3]
