Adsorption is a wellestablished method for heavy metal removal, with biosorbents emerging as an eco-friendly and costeffective alternative to synthetic adsorbents. In this study, water hyacinth (WH) powder extracted from live plants was explored as a natural biosorbent for removing Cr(III) from synthetic contaminated water.enAdsorptionbiosorbentEichhornia crassipesisothermpoint of zero chargeArticle
