Abstract
In this study, we coated the polypropylene filter with titania sol and investigated various characteristic such as its deodorization efficiency and sterilization effect of gram negative bacillus Escherichia coli(ATCC 25922) and gram positive bacillus Staphylococcus aureus(ATCC 6538). As the results, in case of titania sol coated polypropylene filter, the deodorization rate of ammonia, trimethylamin and acetic acid which cause indoor air pollution was 66%, 90% and 16% respectively. Also. the sterilization rate of gram negative bacillus Escherichia coli(ATCC 25922) and gram positive bacillus Staphylococcus aureus(ATCC 6538) was 99.9% after 24 hours.
