Soil is an important part of the ecological environment. As the main carrier of agricultural production, its quality directly affects the quality of agricultural products. In recent years, the problem of soil pollution in China has become more serious. The country has introduced a series of policies to solve this problem. On May 28, 2016, the State Council issued the Action Plan for Soil Pollution Prevention and Control, abbreviated as 'Tokuji Ten'. Since then, laws and regulations on the prevention of soil pollution and other laws and regulations have also been drafted and formulated. Soil remediation work began on a large scale throughout the country.
In the soil anti-fouling treatment work, it is particularly important to carry out analysis and detection of heavy metals in the soil. The pretreatment of samples is one of the key links. At present, the microwave digestion instrument has been widely used in the pretreatment of soil samples.
The task of soil testing is arduous
According to the requirements of 'earth ten', all localities must complete detailed investigation of the soil pollution of agricultural land before the end of 2018. Now that most of 2018 has passed, the detailed investigation of soil pollution in agricultural land has entered a critical period. China has a vast territory, There are many different soil substrates in different areas, with large differences in composition. Soil pollution investigations must be completed within a short period of six months, which can be described as tight time and heavy tasks. In addition, soil samples to be tested and analyzed are mostly deposited through complex actions. The product contains both heavy metals and pesticide residues. The matrix components are very complex and difficult to detect. Therefore, in the soil sample testing, advanced treatment methods and treatments instrument It is very important.
In the determination of soil heavy metal content, there are many sample pretreatment methods. Conventional soil sample digestion methods are complicated to operate, time-consuming and laborious, and the samples are easily lost in the digestion process and cause cross-contamination. Microwave digestion uses microwaves as a heat source for decomposition tests. In addition, the combination of microwave-assisted digestion sample and closed pressurization sample can shorten the time of sample dissolving, reduce the amount of reagents, reduce environmental pollution and energy consumption, and fundamentally improve the sample. The processing efficiency guarantees the accuracy of the test results.
The microwave digestion instrument has a broad market. Enterprises should speed up the layout
At present, the overall situation of the soil environment in China is very unsatisfactory. Soil pollution in some areas is relatively serious. The pressure exerted by the development of industry and agriculture on the soil persists. With the continuous discovery of new chemical pollutants, the prevention and control of soil pollution will undoubtedly become a Long-term and arduous engineering. As an important tool in soil anti-fouling treatment, the market size of microwave digestion instrument is expected to grow rapidly.
In recent years, many scientific research and monitoring agencies have stepped up their procurement efforts and used microwave digestion equipment to conduct research and inspections. Fujian Academy of Agricultural Sciences Institute of Agricultural Quality Standards and Testing Technology, China Agricultural University and other organizations have issued tender information to purchase. According to statistics, the microwave digestion apparatus has reached a sales volume of 3,000 units per year and is still growing. The market prospect is worth looking forward to.
At present, there are mainly microwave digestion instrument manufacturers in the domestic market, such as Jinan Haineng, Shanghai Xinyi, Shanghai Xintuo, Opuler, Anton Paar, CEM, Jena, etc. They continuously improve product technology, strengthen market promotion, and actively participate in the market. Competition for market share. Nowadays, the microwave digestion instrument market is in a period of rapid growth. The relevant instrument companies can take advantage of the situation, enhance their competitive advantages and gain more opportunities for development.
In April 2018, the Ministry of Ecology and Environment issued the "Extraction of Soils and Sediments, Organics-Microwave Extraction Method" (Draft for Soliciting Opinions). This forthcoming new standard will enable microwave digestion to be more widely used in soil testing. Application. We have reason to believe that in this context, microwave digestion instrument market will usher in better development.
