The alkaline activation could be useful to improve the adsorption abilities of hydrochars. In this
regard, the aim of this work was a comparison of the efficiency of non-modified (HPL) and modified
hydrochar (MHPL) forms during the adsorption of cadmium (Cd) ions from aqueous media. It was
found that MHPL had a higher capacity (qm=19.60 mg/g) and a different mechanism of bonding than
HPL (qm=11.76 mg/g). The Langmuir isotherms model best described Cd(II) adsorption by HPL, while
the Freundlich isotherm model better-described adsorption by alkali modified form. The SEM/EDS
and the FTIR analysis confirmed that there is a structural difference between these two new
adsorption materials, which might be attributed to the influence of the NaOH treatment. Also, the
FTIR analysis showed that MHPL adsorbent most binds Cd ions using oxygen functional groups. It
can be concluded that this paper also confirmed that alkaline modification improves the adsorption
capacity of hydrochar.
