Abstract: Recently, a renewed interest in techniques for heavy metal removal of wastewater has been growing because of embarking opportunities for industrial applications. We investigated the adsorption... hydrogel shows faster adsorption kinetics for removing heavy metals from aqueous solution [24]. Recently, several research groups have investigated the removal of Cu with different types of adsorbent......

: phytoremediated giant reed; pyrolysis; biochar; heavy metal; stabilization 1 Introduction Giant reed (Arundo donax), a type of perennial rhizomatous grass widely distributed in South China, is used to stabilize heavy metals in metal-contaminated soils [1,2]. Because of its rapid growth and high biomass yield, giant reed has been explored as an option for phytoremediation, particularly, of soils polluted......
