The study on acetic acid odor removal by titanium

Abstract

There are various odors in hospitals, and reducing unpleasant odors is preferable. Both the quality of medical care the hospital environment are preferable.For example, acetic acid is widely used in hospitals, and it is preferable to reduce the odor.In this study, the decrease of odor molecules and the increase of decomposed molecules were measured when the reduce of acetic acid and increase the decomposition by titanium oxide by measuring the acetic acid concentration, CO2 concentration and H2O concentration.The sensory measurement was conducted by diluting the odor gas to quantify the odor intensity by human nose.Then, a decrease in acetic acid odor was confirmed over time.From these quantitative measurement results, it was possible to quantitatively confirm the decomposition of acetic acid by titanium oxide.
