Water Purification Techniques Using Polyurethane Coated with Silver Nanodots for Clean and Healthy Environment
631–635 (2023)

PACS numbers: 81.20.Ym,81.70.Fy,87.19.xb,87.64.M-,87.80.Qk,87.85.Rs,92.40.qc

In this study, a filtrate system for water purification is developed using polyurethane foam (PUFS) coated with silver nanodots synthesized using monosaccharide sugars. Repetition of washing and drying results in stable PUFS with uniform coating. Highly antiresistant E. coli bacteria of 100 colony-forming units per ml are prepared to be used for testing. Silver-nanodots-coated PUF filter is soaked in this water for 20 minutes and analysed. The result shows very high reduction in bacterial population. This ensured pure drinking water can be obtained by this method at very low cost. Drinking water treatment using silver nanodots paves way for a healthy and safe living for mankind at places, where this precious commodity is.

Key words: polyurethane foam, silver nanodots, E. Coli, water purification, health issues.
