Application and application method of sodium percarbonate as meson fossil extraction process

Abstract

The invention relates to application and an application method of sodium percarbonate as an extraction process of meson fossils; according to the application, sodium percarbonate is used for sample dispersing treatment of the meson fossils, and the sample dispersing treatment comprises the following steps: S1, performing material taking: taking a clean container, measuring a proper number of sodium percarbonate particles, and pouring the sodium percarbonate particles into the bottom of the container; S2, performing submerging: covering the sodium percarbonate particles with the rock fragments containing the meson fossils, and then adding a proper amount of clear water until the rock fragments are submersed by the water surface; and S3, performing sample dispersing: releasing sodium percarbonate particles when meeting water to release bubbles, enabling the bubbles to permeate into fine pores of the rock fragments, slowly expanding the rock fragments, enabling the rock fragments to be in a loose state, and therefore loose sediments are formed; the method further comprises a heating step. The reagent selected by the invention is low in risk and convenient to store, the experiment cost can be greatly saved, and the experiment can be smoothly carried out.

Description

technical field [0001] This patent applies to the technical field of paleontology extraction, more specifically, relates to the application and application method of sodium percarbonate as an extraction process for ostracod fossils. Background technique [0002] The existing ostracod extraction techniques are: [0003] Ostracod fossils are a common micro-paleontological fossil with important geological significance in geological research. It has important indicating significance for the determination of stratigraphic age, the study of paleoenvironment, and the exploitation of oil. However, micro-paleontological fossils are generally invisible to the naked eye (generally less than 1mm in diameter), and cannot be collected and studied like large fossils. They usually occur in sediments, and the sediments that buried them are usually collected together during research, and then extracted through a series of methods in the laboratory to obtain the fossil specimens required for ...

Problems solved by technology

However, when high-concentration hydrogen peroxide encounters heat, bumps or light during transportation or in the laboratory storage process, its reaction can be accelerated to produce a large amount of gas, which is likely to cause an explosion (there has been a laboratory explosion injury accident). Avoid light and heat insulation treatment, which has very high requirements for transportation and storage

[0012] 3. Hydrogen peroxide is in a liquid state, and it is easy to splash and corrode the skin during the experiment stirring, which is harmful to human health

[0013] 4. Naphtha (naphtha) is flammable, and its vapor can form an explosive mixture when mixed with air; the flash point is very low, and it is ineffective to extinguish the fire with water.

[0014] 5. The two reagents, hydrogen peroxide or naphtha (naphtha), are more expensive. Generally speaking, it takes about RMB 10 to process a sample of hydrogen peroxide. However, in geological research, it is often necessary to process dozens or even hundreds of reagents in one experiment. One sample, that is, one experiment will cost hundreds of thousands of yuan, the cost of the experiment is too high, and the expenditure on funds is relatively large
