Biomass-Derived Adsorbents for Dye and Heavy Metal Removal from Wastewater

Wastewater has a high concentration of dyes and heavy metals, which are the two most significant contaminants. Due to their high toxicity and vulnerability, they possess a potential threat to human health as well as the ecosystem. There are many ways to eliminate these pollutants from water but adso...
