RESUMEN
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). The data was retrieved from the Scopus database and analyzed using VOSviewer software to determine the relationship between keywords from each published document. The results of this research was divided into three parts: 1) publication output, 2) global research, and 3) keyword research. From the data obtained, it was found that there has been an increasing research trend of adsorption of lead using water hyacinth, although it is not significant and fluctuating. Overall, this study can be used by researchers to quantitatively assess trends and future directions of this research topic.
