Water pollution caused by inorganic and organic compounds affects seriously health risks and the destruction of the water balance of the ecosystem. Water remediation is one of the greatest challenges of the modern age, which is faced by several countries in over the world. Many advanced technologies have been developed in recent years to manage this alarming problem. One of the recent research directions is to utilize agricultural waste, which is an abundant, low-cost, eco-friendly source, to manufacture cellulose aerogels for the removal of heavy metals, dyes, and oils from contaminated water. This review paper focuses on the latest green fabrication of bio-aerogels from various cellulose-based plant waste and studies on the kinetics and influence of factors such as contact time, pH solution, initial concentration, and temperature on the adsorption process to better understand the mechanisms of water treatment by the cellulose aerogels. Based on the discussion and summary, the potential of agro-waste sources in their value-added chain by developing efficient water treatment cellulose aerogels is comprehensively overviewed.
