Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, in particular to a device for rapidly leaching soil cations. Background Technique

[0002] The cation exchange capacity of soil refers to the total amount of various cations that can be adsorbed by soil colloids. When measuring the cation exchange capacity, the total amount of exchangeable bases in the soil is measured. According to the cation exchange capacity and the total amount of exchangeable bases, the base saturation is calculated. The measurement of the cation exchange capacity of soil is affected by many factors, such as the nature of the exchanger, the concentration of the salt solution, pH, leaching method, etc. At present, the main methods for measuring the cation exchange capacity of soil are the ammonium acetate method, the ammonium chloride-ammonium acetate method, the sodium acetate method and the calcium acetate method. When using an exchange solution such as ammonium chloride-ethanol, the exchangeable cations and soluble calcium, magnesium, potassium and sodium ions in the sample enter the solution at the same time. After the exchange, the excess ammonium salt in the sample is washed, and then the cation exchange capacity is measured by the distillation method or the titration method. The pretreatment of ores or non-metallic materials, such as bentonite, attapulgite clay, sepiolite clay, rectorite clay, zeolite, etc., is similar. After the exchange with the exchange solution, the excess ammonium salt is washed, and then the subsequent operations are carried out. When measuring the cation exchange capacity, the common problems at present are that the pretreatment operation process is complex, the natural leaching process takes a very long time, and the repeated manual treatment seriously affects the production efficiency. Due to the increase in the treatment process, it is easy to cause operation errors and make the measurement results on the low side. Therefore, a device for rapidly leaching soil cations is needed.
