Abstract: Water is a critical substance for existence on earth, and if it is contaminated with pollutants, it will be impossible to survive. There are many techniques to remove the heavy metals present in water including chemical, physical, and biological processes. Today, biocomposites have been able to offer new solutions in the field of treatment of polluted waters. biocomposites have unique properties such as environmental friendliness, high porosity, and high mechanical strength. Polymer composites incorporating biomaterials have been widely studied for wastewater treatment because of their simple preparation, affordability, and resilience. In this research, aloe vera/ nanocellulose/bentonite (A.vera/NC/Bn) biocomposite scaffold was synthesised. this study aims to use this biocomposite scaffold to remove arsenic as a heavy metal in water, also by optimising the conditions such as the contact time of the biocomposite with contaminated water, adsorbent dosage, pH, and temperature, we can achieve better results.

Keywords: wastewater; arsenic; biocomposite; adsorption; aloe vera; nanocellulose; bentonite.
