Trends on adsorption of lead (Pb) using water hyacinth: Bibliometric evaluation of Scopus database.

Heavy metals (Cd, Ni, Zn, Cu, Cr, and Pb) are widely recognized as being hazardous to human health and environmentally deleterious. Therefore water hyacinth is used as a greener adsorption material. This study is a bibliometric analysis of research developments on the adsorption of lead (Pb) using water hyacinth (1995-2023).
