Determination of Carbonate and Bicarbonate in Soil Samples by Centrifugal Separation and Dual Indicator Method
This article optimizes the preparation method and indicator selection of soil leaching solution,selecting centrifugal separation as the preparation method of leaching solution,phenolphthalein as the indicator for carbonate titration endpoint,and bromophenol blue as the indicator for bicarbonate titration endpoint.Good results have been achieved in the determination of CO-23 and HCO-3 in soil.The resutls provide impor-tant reference basis for the ongoing soil popularization testing work.
