DEVELOPMENT OF SOIL SOLUTION EXTRACTION METHOD FOR MULTI-ANALYTE ANALYSIS

摘要

A method for extracting soil solution is provided to measure NH4+, K+, Ca^2+, Mg^2+ and Na+ using leachate at once. A leachate in soil solution extraction method for analyzing multi component is single leachate. The leachate is HCl, LiCl, LiOAc, BaCl2 and BaOAc. The range of each concentration of HCl, LiCl, LiOAc, BaCl2 and BaOAc is 0.1-3M. The leachate contains 0.1M HCl, 1M LiOAc, 1M LiCl, 0.5M BaCl2 and 0.5M BaOAc.
