Biopolymers are polymers that originate from biological sources. Due to their renewable biodegradability and abundance, they present themselves as a high potential source of innovation for several industrial applications. Polysaccharides, and in particular cellulose, today arouse great interest due to its high abundance, wide distribution, and low cost. It is considered one of the most popular organic polymers and an almost eternal source of raw materials for the growing demand for environmentally eco-friendly materials. First, we evaluated the biological activity (Antioxidant and Antimicrobial) of aqueous and organic extracts of Artemisia herba-alba. Second, we extracted and isolated cellulose from the stems and leaves of this plant. Third, the cellulose was modified to improve its solubility and activity using an acrylamide compound. Finally, we investigated the ability of cellulose acrylate to trap copper(II) ions in water. The objective of the study is to promote and maintain an eco-friendly environment with emphasis on water as a vital source.
