| Abstract: | Sulphate ion in environmental water samples was successfully determined by flow injection spectrophotometry, based on the reaction with barium dimethylsulphonazo (III) complex. The linear range is 1-4 mg/L, the recoveries are 95-106%, relative standard deviation is 1.5% (n = 10) and the precision of the procedure for long time (about 4h) < 5%, respectively. |
