Abstract:
... BACKGROUND: In the present work, Hg (II) is considered as one of the most dangerous elements being released excessively into the environment from various sources. Therefore, the aim of this study is the removal of Hg (II) from wastewater effluent by synthesizing a magnetic chitosan modified with glutaraldehyde (MCS‐GA) as an adsorbent. The composite structure was characterized using SEM/EDAX, FTIR ...
