Abstract

The invention discloses a method for measuring the absorptive capacity of plant leaves to particles and adsorption particle size grades. The method includes the steps of ultrasonic washing and filtering, wherein in the filtering step, filter membranes of different aperture grades are sequentially used for filtration, the filter membranes are weighed before and after performing filtration, and the weight and the grade the adsorption particles can be calculated. By means of the technical scheme, particle sizes of the surfaces and wax layers of the leaves can be measured grade by grade, and environmental management is greatly helped.

Description

technical field

[0001] The invention relates to the measurement technology of particle sedimentation, in particular to the measurement method for the adsorption of different particle diameter particles in the atmosphere by different plant leaf surfaces and waxy layers. Background technique

[0002] Since plant leaves have the ability to settle and absorb particulate matter in the atmosphere, they are an effective means of purifying the air. Therefore, we should effectively use plants with large adsorption capacity to purify the air. It also triggered the research on the adsorption capacity of plant leaves.

[0003] Particulate matter in the atmosphere can be classified according to particle size, and the smaller the particle size, the greater the impact on human health. However, the existing methods for measuring the adsorption capacity of leaves can only simply measure the total amount of particles blocked and adsorbed on the surface of the leaves, and cannot accurately cl...
