Cigarette butt waste as material for phase inverted cellulose acetate membranes synergistically incorporated with silver/copper oxide (CA-Ag/CuO) for reverse osmosis water treatment
Key Points
This research aims to explore the use of upcycled cigarette butt cellulose acetate for creating membranes that aid in water purification.
Utilized cellulose acetate from discarded cigarette butts to construct membranes.
Incorporated silver and copper oxide to enhance membrane properties.
Evaluated the effectiveness of the membranes in reverse osmosis water treatment processes.
Membranes demonstrated improved filtration capabilities for water treatment.
The incorporation of silver and copper oxide enhanced antimicrobial properties.
Findings indicate potential for reducing cigarette butt waste while addressing water purification needs.
Abstract
The improper disposal of cigarette butts presents a significant environmental challenge, yet their cellulose acetate (CA) content offers the potential for upcycling into functional materials.
