What plants have stronger adsorption capacity?

For example, the leaves of Salix davidiana are almost flat in the air, so the atmospheric particulate matter per unit area has a strong retention effect.

The retention efficiency (quantity) of different plants to atmospheric suspended particles is different. The amount of suspended particles intercepted by plant leaves is related to the flatness and landing angle of the leaves (that is, the inclination of the leaves). Although the leaf surface of loquat tree is large, its landing angle is almost 45 degrees, so the retention effect of leaves on atmospheric particles will be relatively weak. The same is true of oleander.

At the same time, the roughness of different plant leaves will also affect the interception of particulate matter.

Extended data

The good purification effect of green plants on some pollutants in the air has been confirmed by scientists' experimental research and practice. The most representative is William Warwell, a scientist of NASA. He spent several years testing the absorption capacity of dozens of different green plants to dozens of chemical compounds, and found that all kinds of green plants can effectively reduce the chemical substances in the air and convert them into their own nutrients.

From a list of anti-pollution green plants published by him, it can be seen that under the condition of 24-hour illumination, aloe removes 90% formaldehyde contained in 1 cubic meter of air; 90% benzene disappears in ivy; Agave can swallow 70% benzene, 50% formaldehyde and 24% trichloroethylene; Eupatorium adenophorum can swallow 96% carbon monoxide and 86% formaldehyde.
