Biosorbent based on rice husk for removing copper and nickel ions from wastewater

<strong>. </strong>The adsorption of<strong> </strong>Cu (II) and Ni (II) ions from aqueous solutions by an adsorbent obtained by treating rice husks with an aqueous solution of monoethanolamine was studied . The structure of the adsorbent was studied using IR spectroscopy. It has been shown that adsorption reaches
