| Abstract |
Emerging organic pollutants (EOPs), such as diethyl
phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only
partially removed in conventional wastewater treatment plants. This
study assesses hydrochars produced by hydrothermal carbonization (HTC)
of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for
removing three representative EOPs at environmentally relevant
concentrations. HTC produced hydrochars with distinct physicochemical
properties and pollutant affinities. SB-hydrochar exhibited the highest
surface area (20 m2/g) and an acidic surface, promoting
adsorption of cationic MB and moderately hydrophobic BPA. VSs-hydrochar,
despite low porosity (<5 m2/g), showed strong affinity
for DEP in real wastewater, achieving 3.8 mg/g (86% removal), likely due
to π–π interactions and matrix effects. WSs-hydrochar displayed lower
porosity but maintained relevant MB uptake. MB showed the highest
adsorption (4.8–4.9 mg/g), while BPA exhibited moderate removal
(1.7–2.6 mg/g). These results highlight the potential of hydrochars as
low-cost, sustainable adsorbents for removing EOP from wastewater. |
