|Title:||Sulphate Preconcentration By Anion Exchange Resin In Flow Injection And Its Turbidimetric Determination In Water|
|Author:||Santos Filha M.M.|
|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 MgSO2- 4/l, a throughput of 50 determinations/hr was achieved, and the relative standard deviation of results was better than 2%. © 1993.|
