Filter paper is a quantitative paper used for filtering and made of pure cellulose treated with hydrochloric and hydrofluoric acid. Seal the flask and keep for 10 to 15 days, during this period the filter paper … Measuring and comparing this chemical resistance across papers involves determining their tensile strength when wetted with reagents of known strength. Filters based on cellulose pulp fibres do usually have large pores that facilitate water percolation but they do not sufficiently remove bacteria through size exclusion; other techniques are therefore needed to achieve a bacteria-reducing effect. Filter Paper. Toilet paper and paper towels are high quality cellulose. However, owing to the unstable immobilization of AgNPs, silver can 2010). Cellulose filters.
