Annotation
Adsorption of heavy metal ions is an important aspect for purifying water from pollutants and ensuring environmental safety. In this study, the adsorption process of heavy metal ions was studied using modified rice husk as an adsorbent. Experimental studies included determining optimal conditions for maximum removal of metals from aqueous solutions, including varying parameters such as contact time and pH of the medium, as well as studying changes in the structure of the surface layer of the resulting adsorbent. The results showed the effectiveness of modified rice husk in the adsorption process of heavy metal ions, highlighting its potential as a promising material for wastewater treatment.
