Recently, there is a growing interest in the utilization of waste biomass to curb its potential negative impact on the environment, which includes CO2 emission and various types of soil pollution. Simultaneously, the development of thermochemical technolo gies for conversion of waste biomass into valuable materials becomes very attractive. Hydrothermal carbonization is proposed as a promising and highly effective technology in this field.
In this paper, grape pomace was hydrothermally carbonized at 220 and 240°C to explore the potential application of derived hydrochars (HC-220 and HC-240, respectively) for removal of Cd(II) and Al(III) from aqueous solutions. Obtained preliminary results showed that adsorption capacities achieved using the HC-220 were 65.25 mg/g for Cd(II) and 17.13 mg/g for Al(III). On the other hand, the HC-240 showed smaller capacities for both examined materials (24.25 mg/g for Cd(II) and 9.0 for Al(II)). Differences in the structural properties of hydrochars pro...duced at different carboniza- tion temperatures could be a reason for this observation. Literature data states that higher temperature causes the formation of energy-dense coal-like hydrochars with dominant aromatic structure. Therefore, material obtained at 240°C had less functional
group on its surface and more aromatic structure compared to the HC-220, and thus
less electron donating sites for metal ions adsorption.
Results from this paper suggest that the grape pomace could be a promising precursor for the production of low-cost hydrochars for adsorption of Cd(II) and Al(III) from wastewaters. Besides, results can be further used for the optimization of the HTC
process parameters to find the most adequate reuse of the waste grape pomace.
