Method Overview

• Used to quantify major anion concentrations in scrubber liquors
• Analyses by Ion Chromatography.

Target Compounds

• Fluoride (F);
• Chloride (Cl); and
• Total Sulfur (SO₄)

Performance Tips

• Liquor collected from in-line filtration (positive pressure);
• Sample preservation (dilution) with borate buffer and formaldehyde preservative.
  • Weigh sample bottle including label and cap to the nearest 0.01 g and record weight;
  • Add about 1 mL of 30% hydrogen peroxide to the bottle;
  • Reweigh bottle (including cap) to the nearest 0.01 g and record weight;
  • Label as "Anion DF with peroxide"
  • Color coding bottles (preservatives) can help with later identification.

Shipping

• Samples may be shipped at ambient temperatures.
• Be sure to include a chain of custody for each shipping container.

Applications

• Mainly for determining the chlorides build-up in FGD liquor;
• A time-saving method when multiple samples are involved.
