  2. Description. the Sulfate is possible using the Ca-ISE and EGTA as titrant. An excess of . aCl2 is added to the water sample to precipitate the sulfate. The not reacted Ba-ions are back titrated with E. TA titrant. The titration curve shows two equivalence points. The first one corresponds to the Ca and the dif.

  3. The absorbance of the barium sulphate solution is measured by a turbidimeters and the sulphate concentration, is measured by comparison of the reading with a standard curve. This paper is review of various methods suggested for turbidimetric analysis of sulphates. Key words: Turbidimetry, Sulphate, Natural water, Minerals, Precipitate ...

  4. 11 Φεβ 2016 · The classic technique for sulfate analysis in an undergraduate quantitative analysis lab involves precipitation as the barium salt with barium chloride, collection of the precipitate by gravity...

  5. sulfate (alum) is used as a sedimentation agent in the treatment of drinking-water. Copper sulfate has been used for the control of algae in raw and public water supplies (McGuire et al., 1984).

  6. The initial solution of sulphates: 2ca. 0.2 mg SO 4-/mL: weigh precisely, using an analytical balance, approx. 0.3 g anhydrous Na 2 SO 4 (dried at 105 C), dissolve it in H 2 O and add water to the total volume 1L. Calculate the exact concentration of sulphate anion in this solution. Determination of sulfates in water using a turbidimeter

  7. The performance of the Dionex IonPac AS22 and Dionex IonPac AS18-4 μm columns was compared for the determination of chloride and sulfate in water and soil samples. The Dionex IonPac AS22 column can be used with isocratic carbonate/bicarbonate eluents and suppressed conductivity detection.
