Phosphate ester-linked carbonized polymer nanosheets to limit microbiological contamination in aquaculture water
Year: 2024
Type: article
Abstract: In this study, we have developed a simple and low-temperature method without using toxic chemicals, to synthesize carbonized polymer nanosheets (CPNSs) that exhibit potent bacterial adsorption capabilities for their use as a filter to remove bacteria from aquaculture water. Sodium alginate (Alg), an algae-derived polysaccharide was pyrolyzed with diammonium hydrogen phosphate (DAHP) in solid state at 180 °C. Initially, Alg underwent dehydration and cross-linking via phosphate ester bonds followed by carbonization resulted in the formation of 2D structured CPNSs with distinct polymeric characteristics. The as-synthesized CPNSs demonstrate a high bacterial adsorption capability toward V. parahaemolyticus and S. aureus. Furthermore, CPNSs can be used to modify ordinary filter paper to make them effective in filtering system. Aquaculture water filtration experiments using CPNSs-modified filter paper revealed an increase in the survival rate (> 50%) of shrimp challenged with V. parahaemolyticus upon circulation through the Alg-CPNSs-modified membrane, demonstrating their potential as a viable aquaculture filter.
