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.

进行了具有高湿强度的泡沫状纤维素滤纸的开发，以用作饮用水过滤器。纤维素泡沫纸对几种细菌的湿强度和抗菌活性（枯草芽孢杆菌MTCC 441（革兰+ ve），蜡状芽孢杆菌NCDC 240（革兰+ ve），铜绿假单胞菌NCDC 105（革兰-ve），肺炎克雷伯菌NCDC 138 （Gram -ve）和大肠杆菌研究了MTCC 40（Gram -ve）。使用扫描电子显微镜（SEM）表征纤维素泡沫纸的形态和结构。我们的研究结果证实，在用阳离子聚丙烯酰胺（C-PAM）预处理的纤维素泡沫纸中添加戊二醛溶液或1,2,3,4-丁烷四甲酸（BTCA）可以提供非常高且稳定的湿强度性能以及出色的抗菌性能。
