Abstract

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 m 2 /g) and an acidic surface, promoting adsorption of cationic MB and moderately hydrophobic BPA. VSs‐hydrochar, despite low porosity (
