Trivalent ChromiumIon Concentration Measurement：

Ø Accurately transfer 25mL of the test solution into a 250mL conical flask. Add sequentially 50mL of pure water, 10mL of 50% sulfuric acid solution, 1mL of concentrated phosphoric acid, 10mL of 1% silver nitrate solution, and 2g of ammonium persulfate. Mix well.

Ø Place on an electric furnace and bring to a boil for about 2 minutes, then cool to room temperature and add 5-6 drops of vanadium reagent.Phenyl substituted o-aminobenzoic acidStir well before use.

Ø Titrate with a 0.1mol/L ammonium iron(II) sulfate standard solution until the color changes from purple-red to yellow-green. At this point, the volume of the 0.1mol/L ammonium iron(II) sulfate standard solution consumed is V.mL，The calculation formula is as follows:：

Tri-valent Chromium Content = (0.1 × V) × 52/3/25 g/L

槽液 Maintenance

Ø Actual production consumption is mostly overflow consumption; the槽液 should be regularly tested during the production process.pH value and trivalent chromium ion concentration.

Ø Long-term use of the槽液 may result in a small amount of precipitation. It is recommended to use an environmentally friendly钝化槽 with a filter machine.
