By the end of 2015, the national soil point exceeding the standard rate was 16.1%, and the over-standard rate of cultivated land points was 19.4%. The soil pollution problems in some areas such as the Yangtze River Delta, the Pearl River Delta, and the old industrial bases in Northeast China are particularly prominent. The soils in the southwest and south-central regions have a large range of heavy metals. After the introduction of “Ten Shi”, 10 provinces will launch pilot demonstration projects for soil pollution control and restoration, and support 38 key prevention and control areas for heavy metals to carry out comprehensive prevention and control demonstrations. The intensity and funding for prevention and control of soil pollution will be strengthened. The period of time will be the most intensive period of soil testing. At the same time, the investment demand for the environmental protection industry during the 13th Five-Year Plan period will reach 10 trillion yuan, and the soil remediation market has a broad space.

In addition to the environmental protection departments (agricultural land and polluted land), the departments that carry out soil monitoring surveys include the agricultural sector (cultivated land) and the national land sector (measuring mineral elements and other inorganic indicators in the soil). Among them, the Ministry of Environmental Protection has set up more than 30,000 national environmental monitoring points for soil environmental quality monitoring and plans to add 7,000 new ones in 2016. The agricultural department has established 107 national-level arable land quality testing points throughout the country, and plans to establish 152,000 National control points for the safety monitoring of agricultural products.

In short, what exactly does “Ten Shi” bring to the analytical instrument?

For the various analytical experiments that appear in the standard, the importance of sample preparation has been widely concerned by the experimental operators. IKA provides you with comprehensive and high-quality solutions, such as: perfect solution to the quantitative distillation demand in the Veterinary Drug test. Evaporators, grinders equipped with non-metallic coated tips, dispersers for hard samples, multi-tube mixers, etc., please visit the IKA website for more information:

At the same time, we can see that organic pollution includes volatile organic pollutants and semi-volatile organic pollutants such as organic pesticides. The pollution of inorganic substances is mainly heavy metals and occupies a large proportion of detection, which is enough to show the current urban and cultivated soil. The worrying state of pollution, it even affects shallow groundwater. Therefore, "heavy metals" can be said to be the top priority of soil remediation.

In recent years, the interaction of metal oxides, especially iron-manganese oxides and heavy metal ions, has been one of the focuses of soil chemistry and environmental chemistry research. Due to the redox of high-valent iron and heavy metal ions such as *, iron oxides and hydroxides The material has a good fixation effect on heavy metal ions such as * in the soil, so different carriers are loaded with high-priced iron. This method is not only applied to the control of heavy metal ions in the soil, but also in universities and scientific research related to the environment and chemistry all over the country. The interior is constantly being optimized.

In the most core scientific research, it is necessary to carry out a suspension of soil samples and environmental materials for up to 12 hours of oscillation. The incubation environment requires simulating the anaerobic conditions of the soil (ie, first introducing nitrogen into the sample bottle to catch oxygen, Reseal the bottle mouth), so the magnetic stirring method that is easy to bring in oxygen is no longer suitable for downstream operation. Instead, we see the KS 4000 ic control type in many laboratories with such livelihood:

Germany IKA provides you with a series of laboratory sample preparation products, which not only make the work efficiency of scientists greatly improved, but also the safety of operation is different. It is also consistent in the major field of soil monitoring and repair.
