Introduction: Soil cation exchange capacity (CEC) refers to the total amount of various cations that can be absorbed by soil colloids. The cation exchange performance of the soil is determined by the surface properties of the soil colloid. It is composed of the exchange base of organic matter and the exchange base of inorganic matter. They combine with each other in the soil to form a complex organic-inorganic colloidal complex, which can be absorbed The total amount of cations includes exchangeable bases (K+, Na+, Ca2+, Mg2+) and hydrolyzable acids, and the sum of the two is the cation exchange capacity. The amount of cation exchange can be used as an index to evaluate the ability of soil to retain fertilizer. Cation exchange capacity is the main source of soil buffering performance and an important basis for soil improvement and rational fertilization. The automatic cation exchange capacity tester is a set of automatic intelligent testing equipment designed according to the classic Kjeldahl principle of nitrogen determination. Mainly used for the determination of cation exchange performance. This product is suitable for food, beverage, medicine, agriculture, forestry and fishery, mining, chemical and other production enterprises, as well as universities, scientific research institutes, environmental monitoring, soil and fertilizer stations, agricultural machinery stations, quality supervision and inspection and other scientific research and testing units for food and dairy products Intelligent determination of nitrogen or protein content in samples such as natural rubber, latex, seeds, soil, plants, feed, ore, sludge and chemical sediments, and determination of soil cation exchange performance Features: 1.
