This product is based on LYT 1243-1999Method for 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

JK9870Ycation exchangeThe fully automatic measuring instrument has been realizedAutomatic addition of reagents, automatic distillation and separation of samples, automatic collection of samples, and automatic titration analysis. productThe built-in formula for calculating cation exchange capacity allows for direct calculation, display, storage, and printing of experimental results without the need for manual calculation
