AB  - In this study, Paulownia tree leaves hydrochars (PL-HTCs) were used as potential adsorbents for
Zn(II), Cd(II) and Mn(II) ions from aqueous solution and their efficiency was investigated. The
preliminary adsorption results showed that hydrochars had better affinity for Cd(II) than for Zn(II)
and Mn(II) ions removal. In order to improve adsorption capacity, hydrochar obtained at 220°C were
activated with NaOH and further investigated only for Cd(II) removal. Alkali activated hydrochar
(AH-220) has significantly better efficiency (q=24.05 mg/g, E=52.57%) in removing Cd(II) ions than
hydrochar before modification. Adsorption kinetic studies showed that Cd(II) ions sorption at AH-220
surface followed the pseudo-second-order model. This implies that the adsorption process was mostly
controlled by the chemical binding.
Keywords: tree leaves hydrochars, adsorption, heavy metals, kinetic studies.
