Fabrication of a symbiotic polyvinyl alcohol-functionalized NiO/rGO nanoadsorbent for control of bisphenol-a removal

Abstract

PVA-NiO/rGO nanoadsorbent was prepared. The as-prepared nanoadsorbent exhibited 98.6% removal efficiency of bisphenol-A (BPA) in aqueous media under optimized conditions, such as pH 9, an adsorbent dose of 2.5 mg, and an 80 mg L −1 BPA concentration.
