Exhaust Detoxifier: An Abstract

One of the major causes of global warming is air pollution. It has greatly damaged our planet and continues to do so. Pollutants come from different sources but mostly are from vehicles' exhaust gases.

This investigatory project aims to lessen the toxicity level of air using a device that is able to filter and detoxify hazardous chemicals produced by combustion. In the researchers' experimentation, they made 4 set-ups using sulfur dioxide and another 4 set-ups using vehicle exhaust. Each set-up has the same components except for the orientation and the medium used to put in the aqueous sodium carbonate solution. A glass design was made to let the researchers look into it and see what is happening while proceeding to the process of burning the sulfur to produce sulfur dioxide or putting samples of vehicle exhaust inside the device.

As this process continues, some of the fume's hazardous components are detoxified and filtered as it flow and passes through the aqueous sodium carbonate solution. It will then mix towards the water vapor. After, the water vapor returned to its original state and is indicated by a blue litmus paper.

The color of the litmus didn't change. This means that the device has a potential in partially detoxifying exhaust gases produced by combustion. And since charcoal has been proven to have the adsorptive property which can capture toxics, the researchers recommend adding it to the device so that it could filter more exhaust gases and produce cleaner air.
