Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific implementation examples, in order to help readers better understand the present invention, but not as a limitation to the implementation scope of the present invention.

[0015] Research on the relationship between the content of endosaccharides in soil and the amount of biomass incineration:

[0016] Wheat stalks, corn stalks, and branches were selected as the cellulosic biomass materials for combustion. The burning amount of each biomass material sets two gradients: 1kg / m 2 、2.5kg / m 2 compared with a blank. Three replicates were set up for each treatment. Soil samples were taken 24 hours after the combustion was over.

[0017] The surface soil (0-5cm) after burning different biomass materials was collected respectively. Dry thoroughly at 55°C and grind through a 60-mesh sieve. Take 5g of soil sample and add it to a 50ml glass bottle, add 5g of diatomaceous earth and mix well. Cle...

Abstract

The invention relates to a quantitative method for combustion quantity of cellulosic biomass during combustion, belonging to the field of environmental monitoring. According to the invention, a specific tracer molecule 1,6-anhydro-beta-D-glucopyranose (hereinafter referred to as levoglucosan) for combustion of the cellulosic biomass is utilized to reflect the quantity of combusted biomass based on the content of levoglucosan in soil. The method comprises selection of the specific tracer molecule for combustion of the cellulosic biomass, acquisition of a soil sample, pretreatment of the sample, extraction and purification of the tracer molecule in soil and trace detection of levoglucosan. With the method provided by the invention, combustion quantity of cellulose in a specific cellulose combustion process (e.g., a mountain fire, a forest fire and burning of residual crops in a farmland) can be conveniently estimated, and the method has application prospects in aspects like environmental monitoring, criminal investigation and archaeology.

Description

technical field [0001] The invention belongs to the field of environmental chemical monitoring, and relates to the selection of specific tracer molecules (1,6-anhydro-β-D glucopyranose) for cellulose biomass combustion, the collection method of soil samples, the pretreatment method of samples, and the indicator The extraction and purification methods in molecular soil, and the trace detection method of 1,6-anhydro-β-D glucopyranose. Background technique [0002] The current issue of global climate change has attracted much attention, and its impact on the entire ecosystem is very important. Various countries also attach great importance to research on greenhouse gases. Cellulosic biomass is the most abundant source of organic matter on the earth. A large amount of organic matter enters the global carbon cycle with the burning of biomass every year and has an important impact on it. The burning of cellulose can release large amounts of greenhouse gases such as carbon dioxid...
