Flow-injection ultraviolet spectrophotometric determination of sulphate in natural waters
The proposed method is based on measurement of the absorbance of the FeSO"4^+ complex cation at 355 nm. Sample-injection and reagent-injection procedures are described. Calibration graphs are linear in the ranges 25-600 and 10-150 mg l^-^1 sulphate, respectively. The main interference is from u...

Flow-injection ultraviolet spectrophotometric determination of sulphate in natural waters |
| abstract |
The proposed method is based on measurement of the absorbance of the FeSO"4^+ complex cation at 355 nm. Sample-injection and reagent-injection procedures are described. Calibration graphs are linear in the ranges 25-600 and 10-150 mg l^-^1 sulphate, respectively. The main interference is from ultraviolet-absorbing organic compounds in the waters. Methods of eliminating the interference are discussed. Results for sulphate in river waters compare satisfactorily with those obtained by the gravimetric method. Depending on the pretreatment used, 10-30 samples can be analyzed per hour. |
