Description

Technical Field

[0001] The utility model relates to the technical field of soil determination, in particular to a novel device that realizes the functions of stirring and cleaning multiple samples at the same time. Background Art

[0002] Cation Exchange Capacity (CEC) refers to the total amount of various cations that soil colloids can absorb, expressed as centimoles per kilogram of soil (cmol+ / kg). Cation exchange capacity is the main source of soil buffering performance. It can adjust the concentration of soil solution, ensure the diversity of soil solution components, maintain the physiological balance of soil solution, and prevent various nutrients from being leached by rainwater. Determining soil cation exchange capacity can not only reasonably fertilize and improve soil, but also has important significance for studying the environmental behavior of pollutants.

[0003] The commonly used method for determining soil cation exchange capacity is the ammonium acetate centrifugal exchange method. The soil is repeatedly treated with ammonium acetate solution under suitable pH conditions (pH 7.0) to make it NH4+ saturated soil. After the excess ammonium acetate is washed away with ethanol, magnesium oxide is added to distill it by the method of nitrogen determination distillation. The cation exchange capacity is calculated according to the amount of NH4+. During the determination process by the ammonium acetate centrifugal exchange method, ammonium acetate and ethanol need to be repeatedly stirred, centrifuged, and washed. The existing method is often stirred by a rubber-headed glass stirring rod. In this way, only one centrifuge tube can be stirred at a time, and multiple tubes cannot be stirred at the same time. It is time-consuming and labor-intensive. The production speed is slow and the efficiency is low when batch samples are processed. At the same time, after the sample processing is completed, a small amount of soil sample will inevitably remain on the wall of the centrifuge tube, causing cleaning difficulties. The disadvantage of the commonly used tube brush is that it can only clean one centrifuge tube at a time, which is also not suitable for batch cleaning. Utility Model Content
