Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Wherein, the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to explain the technical solutions of the present invention.

[0041] The present invention can be classified as solving three problems: one is to measure the total amount of particles adsorbed by the leaves; the other is to measure the amount of particles on the leaf surface and the waxy layer respectively; The amount of particulate matter of different particle sizes on the leaf surface and waxy layer were measured respectively.

[0042] We describe the specific implementation process of the method of the present invention with the following examples.

[0043] 1. Measurement purpose:

[0044] Measure the amount of particulate matter settled on the leaf surface and waxy layer of a certain plant leaf, and i...

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...
