This product is based on the method of "LYT 1243-1999 Determination of Cation Exchange Capacity of Forest Soil", using 1mol/LRepeatedly treat the soil with ammonium acetate solution to make it saturated with ammonium ions, and use 95% excess ammonium acetate solutionWash with ethanol, then add magnesium oxide for distillation. The distilled ammonia is absorbed by boric acid solution and titrated with standard acid solution. The soil cation exchange capacity is calculated based on the amount of ammonium ions

JK9830YcationautomaticThe measuring instrument realizes automatic addition of reagents, automatic distillation and separation of samples, automatic collection of samples, and automatic stop of distillation. productBuilt in cation exchange capacity calculation formula, manual input titration volume instrument automatically calculates, displays, and stores experimental results without manual calculation
