Method for rapidly measuring soil replaceable Kali content using trispectral photometer and converting measured value to ammonium acetate method Replaceable Kali content

摘要

In the present invention, the soil is leached with sodium chloride (NaCl) solution to quickly measure the substitutional Kali content of the soil with a spectrophotometer, and the substitution of the ammonium acetate method (NH ₄ OAc method), which is conventionally used as a standard method in Korea. The present invention relates to a method capable of converting to a carboxylic acid content, the present invention is simpler to prepare a reagent compared to the conventional method, and because the addition of the reagent for analysis in drops or spoons, the analysis operation is simple, saving time and expensive The use of a low-cost spectrophotometer in place of the atomic absorption spectrometer makes it possible to reduce the cost of measuring equipment due to the low cost of measuring equipment, and to significantly reduce the amount of waste liquid generated after analysis due to the low amount of reagents. By using reagents that do not contain nitrogen as a contaminant, it is possible to significantly reduce environmental pollution.
