Sustainable Natural Materials Used for Adsorbing Pollutants from the Aqueous Medium

This chapter continues a discussion on the second sustainability level of environmental protection technologies and focuses on the use of natural materials for removing pollutants (for example, potentially toxic elements) from the aqueous media. This chapter describes PTEs found in waters and the use of biochar as a sustainable material for removing them. This part of the book looks into the adsorptive capacity of biochar and the effectiveness of contaminant removal subject to its type and the characteristics of the adsorbable material. Moreover, the influence of biochar composition as an adsorbent on its capacity is analysed with respect to syngenetic elements.
