Determination of Sulfate in drinking, surface and waste water. 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.
Sample. A sample solution containing less than 20 mg sulfate is diluted with 50 mL deionized water. The pH is measured and if necessary adjusted to pH 3–4 with c(HCl) = 1 mol/L. 7.50 mL c(BaCl2) = 0.05 mol/L is added and after a reaction time of 3 min 5 mL buffer solution is added.
15 Σεπ 2019 · turbidimetric method can be used to determine sulphate ions in water samples where their concentration is low and does not contain carbonate ions, which give significant interference.
• Deionized water 1. Prepare a 70-mg/L sulfate standard solution as follows: a. Use a pipet to add 7.0 mL of 1000-mg/L sulfate standard solution into the volumetric flask . b. Dilute to the mark with deionized water . Mix well. Prepare this solution daily. 2. Use the test procedure to measure the concentration of the prepared standard ...
