摘要:

High Performance Ion Chromatography (HPIC) methods for measuring sulfate in 20 mMphosphate extracts of soil need to cope with low sulfate (down to 0.1 ppm S) in up to 5000 times the molar concentration of phosphate and potassium or calcium, a diversity of solutes including organic compounds, and colloidal particles.
