Schematic of metal removal using metal oxides prepared by green synthesis. Left—a digital images and b absorption spectra of neem bark extract-mediated silver NPs (NB-AgNPs) with different metal ions and concentration-dependent studies of c Hg2+ and d Zn2+. Right—a digital images and b absorption spectra of fresh mango leaf extract-mediated silver NPs (MF-AgNPs) with different metal ions and c concentration-dependent studies of Pb2+ removal [147]
