“…Synergies between biological invasions and other drivers of ecosystem degradation exacerbate current invasions and increase their scope and impacts (Pyšek et al 2020). Once invasive plants become dominant, they can displace native vegetation and disrupt the original ecosystem (Zhou et al 2023). In recent years, some researchers have demonstrated that invasive plant species can also be used to prepare biochar to remove pollutants from water (Li et al 2023;Wang et al 2023b).…”

In this work, an invasive plant (Aster subulatus Michx) mesopore laminar biochar loaded with transition metal Co (CoS@MLBC) was synthesized by a one-step hydrothermal carbonization way for activating peroxymonosulfate (PMS) to remove antibiotics in water. We characterized the structure and morphology of CoS@MLBC and tested its performance. The results showed that the carbon nitride structure was formed on CoS@MLBC, which improved its adsorption capacity for antibiotics and PMS. In addition, Co-doping significantly enhanced the PMS activity and efficiently degraded ciprofloxacin (CIP) over a wide pH range. It was identified that radical and non-radical synergistic action had a critical effect on the CIP degradation process. Furthermore, CoS@MLBC could completely remove CIP within 10 min and had a high removal efficiency (98%) after four cycles. Three possible pathways of the CIP degradation process with 12 intermediates were proposed and their ecotoxicity was analyzed. This work provides a new perspective for preparing biochar from invasive plants for the degradation of antibiotics in water, realizing the concept of “treating the wastes with wastes”.

The Coronavirus disease pandemic over the last three years has shifted the attention of the entire world population from a self‐centred monitory growth to a holistic growth, with health and environment as the central focus. Pharmaceuticals and microplastics have emerged as most prominent environmental contaminants in recent times. Although adsorption is recognized globally as a low cost and effective remediation process, the removal of a variety of pollutants from environmental niche still remains a challenge. This review highlights the use of valorised waste aquatic biomass as an adsorbent for the withdrawal of various emerging pollutants (pharmaceuticals, microplastics and heavy metals). The unwanted invasive aquatic plants can be used as a valuable resource and converted into an ideal precursor and value product for the development of carbon‐based adsorbents that have numerous industrial and environmental applications. There lacks a comprehensive review and analysis on the use of biochar, derived from aquatic biomass, for the extraction of emerging pollutants, especially for microplastics. This distinctive, timely work will aid in the expansion of research on the production of biochar from a waste resource, strengthen their use as adsorbent and help combat the increasing pollution due to various emerging pollutants, including pharmaceuticals and microplastics.This article is protected by copyright.
