Description
A method for bio-available sulfate analysis in soils is described. A Ca(H2PO4) leaching solution was used for soil samples treatment. A standard NaSO4 solution was used for preparing a calibration curve and also the fundamental parameters method approach was employed. An Am-241 (100 mCi) source and a Si-Li detector were employed. Analysis could be done in 5 minutes; good reproducibility, 5 and accuracy, 5 were obtained. The method is very competitive with conventional nephelometry where good and reproducible suspensions are difficult to obtain. (author)
