چکیده
Air filters are crucial components of a building ventilation system that contribute to improving indoor air quality, but they typically associated with relatively high pressure drops. The purpose the study is evaluate effect additives on ultrathin electrospun filters, drop, and particle removal efficiency uniformly charged particles. fibres were under optimised conditions resulted in fast-fabricating process due properties cellulose acetate solution. Different fibre based (CA) fabricated: pure CA filter, two separately doped activated charcoal (AC) titanium dioxide (TiO2), respectively, composite filter where additives, AC TiO2, embedded between layers. exhibited low drop 63.0 63.8 Pa at face velocity 0.8 m s−1. filtration performance particles showed above 70% for sizes 0.3 0.5 μm all rising 90% larger 1 10 μm, which translates average pollens other allergenic contaminant Due positive impact morphology caused by highest among produced reaching 82.3% towards smaller up 100% 5 μm. Furthermore, itself not source microparticles fully biodegradable compared polymers commonly used filters. These expected be practical applications better environments.

Studies of Electrospun Cellulose Acetate Nanofibrous Membranes
The objective of this work was to study the feasibility of preparing cellulose acetate (CA) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. CA solutions in dichloromethane (DCM), formic acid, acetic acid and trifluoroacetic acid (TFA) were electrospun into nonwoven fiber membranes, respectively. The scanning electron microscope (SE...
متن کاملExperience with cellulose acetate-coated activated charcoal haemoperfusion in the treatment of severe hypnotic drug intoxication.
A haemoperfusion column containing activated charcoal coated with cellulose acetate was used to treat 7 patients with barbiturate or ethchlorvynol poisoning. Six of the patients showed marked lightening of coma and all showed a significant fall in plasma drug concentration. Plasma drug clearance and platelet loss were similar to those reported for other coated charcoal columns. Cellulose acetat...
متن کاملA hemoperfusion column based on activated carbon granules coated with an ultrathin membrane of cellulose acetate.
A hemoperfusion system has been developed which makes use of activated carbon encapsulated with cellulose acetate. Studies have revealed that there are no stagnant flow regions in the column, there is minimal particle release and the coating is 30 A thick. The relationships between pore size, pore volume and surface area have been examined. Twenty-five patients in grade IV coma have been treate...
متن کاملEnhanced visible-light photocatalytic performance of electrospun carbon-doped TiO2/halloysite nanotube hybrid nanofibers.
In this work, the effects of halloysite nanotubes (HNTs) on the visible-light photocatalytic ability of electrospun carbon doped TiO2/HNT (C-TH) nanofibers have been explored. Structural and morphological investigations demonstrate that incorporation of HNTs into anatase C-TH hybrid nanofibers was easily achieved by using sol-gel processing combined with electrospinning approach, thus HNTs coul...
