Sustainable removal of phenol from polluted wastewater using phosphoric acid activated biochar prepared from date kernels
Phenolic compounds are among the most hazardous organic pollutants commonly detected in industrial wastewater due to their toxicity, persistence, and resistance to biodegradation. In this study, phosphoric acid-activated biochar derived from date kernels (DK) was synthesized as a sustainable and low-cost adsorbent for...
