Abstract
). Notably, the method achieved a high enrichment factor of 87-fold in real wastewater samples. The environmental friendliness of the protocol was validated by an AGREE score of 0.76. This work represents the first successful application of an acetic acid-based HDES for Cr(vi) removal, establishing a scalable, efficient, and green methodology for environmental remediation.
