<P><B>Abstract</B></P> <P>Development of a foam-formed cellulose filter paper with high wet strength was carried out for application as a drinking water filter. The wet strength and antimicrobial activity of cellulose foam paper against several bacteria species (<I>Bacillus subtilis</I> MTCC 441 (Gram +ve), <I>B. cereus</I> NCDC 240 (Gram +ve), <I>Pseudomonas aeruginosa</I> NCDC 105 (Gram −ve), <I>Klebsiella pneumonia</I> NCDC 138 (Gram −ve), and <I>Escherichia coli</I> MTCC 40 (Gram −ve)) were investigated. The morphology and structure of the cellulose foam paper were characterized using scanning electron microscopy (SEM). The results of our study confirmed that glutaraldehyde solution or 1,2,3,4-butanetetracarboxylic acid (BTCA) added to cellulose foam paper pretreated with cationic polyacrylamide (C-PAM) provided very high and stable wet strength performance together with excellent antimicrobial properties.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Development of novel porous cellulose foam filter paper. </LI> <LI> Improving wet strength using Glutaraldehyde and BTCA along with C-PAM. </LI> <LI> Evaluation of antibacterial activity against gram positive & negative bacteria. </LI> <LI> Morphological and structural analysis of developed paper using SEM. </LI> </UL> </P>

<P><B>Abstract</B></P> <P>Filtration is a promising water treatment method to purify drinking water. To develop highly efficient drinking water filter paper, water-resistant cellulose foam paper with a high wet strength property was fabricated using diverse metal oxide (e.g., copper oxide (CuO), zinc oxide (ZnO), and silver oxide (Ag<SUB>2</SUB>O)) nanoparticles. These nanoparticles were synthesized using the hydrothermal reaction method. Their morphological structures were studied using a field emission scanning electron microscope (FESEM). The presence of coated nanoparticles on the cellulose foam filter was verified by energy dispersive X-ray spectroscopy (EDX) methods. The antibacterial performance of different types of modified cellulose foam filters was studied against <I>E. coli, P. aeruginosa, B. subtilis,</I> and <I>B. cereus</I> strains using the zone of inhibition test. The antibacterial profile of the cellulose foam filter impregnated with Ag<SUB>2</SUB>O nanoparticles, when tested against different types of bacteria, exhibited higher antibacterial activity than the cellulose foam filter impregnated with ZnO and CuO nanoparticles.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Facile synthesis of nanoparticles using hydrothermal method. </LI> <LI> Impregnation of nanoparticles in water-resistant cellulose foam paper. </LI> <LI> Morphological, structural, and elemental characterization using SEM and EDX. </LI> <LI> Antibacterial evaluation of impregnated paper against gram positive and gram negative bacteria. </LI> <LI> Enhanced antibacterial profile of nanoparticle modified filter paper compared to unmodified paper. </LI> </UL> </P>
