Globally, human activity and fast modernization have an impact on the ecological economic aspects. These factors led to generation of complex wastewater consisting recalcitrant toxic carcinogenic contaminants. The inaccuracy traditional treatment techniques using adsorbents lower concentration pollutants below desired standards has paved way for technological advancements in synthesis method operating conditions. Hence, this become highly imperative utilize effective advanced remediation strategies removal pollutants. Several were put forth because their unique characteristics such as affordability, adaptability, simplicity use. present review article organizes scattered available information potential abundant biomass-derived low-cost It been discovered that are extremely effective, alternative, carbon–neutral offering a new perspective modular adsorption process.
