|Title:||SULFATE PRECONCENTRATION BY ANION-EXCHANGE RESIN IN FLOW-INJECTION AND ITS TURBIDIMETRIC DETERMINATION IN WATER|
|Abstract:||A preconcentration procedure was established for sulphate determination in rain waters at the mg/l level, employing a small column packed with the AG1-X8 (200-400 mesh) anionic resin inserted into a flow injection system. Sulphate determination was performed by using the turbidimetric method based on reaction with barium. For concentrations within 0.10 and 2.0 mgSO42-/l, a throughput of 50 determinations/hr was achieved, and the relative standard deviation of results was better than 2%.|
