  Abstract

Materials containing silver nanoparticles (AgNPs) are of great interest for household uses, including drinking water disinfection. Although various Ag-containing materials are available, the development of low-cost, reusable, and durable systems is a challenge in water disinfection. Herein, we developed a low-cost, reusable, and durable cellulose filter paper (CFP) containing AgNPs decorated with a tannic acid (TA) and chitosan (CS) matrix (CFP-CSTAAg). The formation of CFP-CSTAAg composite was confirmed by FTIR, and XRD techniques. The formation of CSTAAg composite on CFP greatly improved the mechanical performance. CFP-CSTAAg is driven by gravity of 100 ml of a water sample containing Staphylococcus aureus for 30 min. The composite showed 99 % killing efficiency of bacteria as the bacteria cells did not pass through composite. The low-cost CFP-CSTAAg composite was reusable, providing a 98 % bacteria-killing capacity after five treatment cycles. The product셲 properties make reusable CFP-CSTAAg composite a promising filter for durable water disinfection as it is a low-cost material and eco-friendly.
