Air Pollution Essay

REDUCTION OF AIR POLLUTION FROM VEHICLES USING TITANIUM DIOXIDE

Abstract—We are facing the pollution menace from vehicles to a greater extent, especially to the people who are living near roadsides. NOx is one of the major pollutant emitted from vehicles. NOx gases react to form smog and acid rain as well as being central to the formation of fine particles and ground level ozone, both of which are associated with adverse health effects. This project entirely focuses on how titanium dioxide coated tiles can reduce the effect of vehicle air pollution and how effectively it does so. This project demonstrates a setup showing the photo catalytic effect of titanium dioxide for reducing the effect of air pollution. This experimental setup consists

Fig 4.2 Experimental Setup with UV Light

A small pipe is connected at one side of the box so that the polluted air can be passed to the box through that pipe. After filling the experimental setup box with polluted air, the pipe is closed with a tight cap so as to avoid the air leakage from the experimental setup.

B. Design of an Experimental Setup without UV Light

Design of an experimental setup without UV light consist of a tile pasted on the wooden box of dimension 27x17x17 cm with an opening at the top portion. The top portion of the wooden box is covered with a glass piece of the dimension 27x17 cm. A hole of 8mm is inserted at the center portion of the glass piece placed at the top of wooden box so as to insert the probe of the gas analyser.
