Abstract

Highlights: Development of novel porous cellulose foam filter paper. Improving wet strength using Glutaraldehyde and BTCA along with C-PAM. Evaluation of antibacterial activity against gram positive & negative bacteria. Morphological and structural analysis of developed paper using SEM. Abstract: 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 ( Bacillus subtilis MTCC 441 (Gram +ve), B. cereus NCDC 240 (Gram +ve), Pseudomonas aeruginosa NCDC 105 (Gram −ve), Klebsiella pneumonia NCDC 138 (Gram −ve), and Escherichia coli 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.
