A critical review of microplastics and nanoplastics in wastewater: Insights into adsorbent-based remediation strategies
This review analyzes research on removing microplastics and nanoplastics from water using materials that absorb the particles, finding that adsorption is the most widely studied removal method. Carbon-based and metal-based materials currently dominate the research, but plant-based (biopolymer) adsorbents are gaining attention because they are biodegradable and non-toxic. Better removal technologies are critical because conventional water treatment often fails to capture the smallest plastic particles that pose the greatest risk to human health.
