Comprehensive evaluation of a slag–activated carbon composite for metformin removal from wastewater and its agricultural reuse potential
Metformin, a widely prescribed antidiabetic drug, persists in aquatic ecosystems and poses toxic risks to nontarget organisms. This study synthesized a novel composite adsorbent from steel slag and activated carbon (2 : 1 ratio) for efficient metformin removal from water, then evaluated the spent adsorbent as a soil am...
