Mechanistic study of bisphenol A removal from water using Fe and HNO3 co-modified clay-based biochar: Adsorption, in situ pyrolytic degradation, and DFT insights.
Bisphenol A (BPA), a typical endocrine-disrupting pollutant, poses a threat to human health. In this study, an Fe and HNO3 co-modified adsorbent was synthesized through the co-pyrolysis of lignin and spent bleaching clay for BPA removal. The effects of initial pollutant concentration, pH, coexisting substances, and reg...
