What gases can sulfur dioxide absorb?

Ordinary plants absorb sulfur dioxide:

Rhododendron: it is an ideal flower to resist pollution such as sulfur dioxide. For example, Rhododendron rockii can germinate and germinate normally at a distance of more than 300 meters from the pollution source of sulfur dioxide.

Hibiscus: It can absorb toxic gases such as sulfur dioxide, chlorine and hydrogen chloride. It can also grow normally at a distance of 0/50 meters from fluoride pollution source/kloc-.

Camellia: flowers can resist harmful substances such as sulfur dioxide, hydrogen chloride, chromic acid and nitric acid smoke, and purify the atmosphere.

Wei Zi: It has strong resistance to toxic gases such as sulfur dioxide, hydrogen chloride, chlorine gas and hydrogen fluoride. Each kilogram of dry leaves can absorb about 10g.

Milan: It can absorb sulfur dioxide and chlorine in the atmosphere. Smoked in the air containing IPPM chlorine for 4 hours, the chlorine absorption of 1 kg dry leaves was 0.0048 g.

Plum blossom: It can monitor the pollution of sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene and aldehyde in the environment. Once sulfide appears in the environment, its leaves will appear mottled or even yellow, which is a wake-up call for people.

Sulfur dioxide (chemical formula SO2) is the most common sulfur oxide. One of the main pollutants in the atmosphere. This gas is emitted when a volcano erupts, and sulfur dioxide is also produced in many industrial processes. Because coal and oil usually contain sulfur-containing compounds, sulfur dioxide will be produced when burned. When sulfur dioxide is dissolved in water, it will form sulfurous acid (the main component of acid rain). If sulfur dioxide is further oxidized, usually in the presence of catalyst, sulfuric acid will be generated quickly and effectively. This is one of the reasons for worrying about the environmental impact of using these fuels as energy.
