3 Method summary
In the sample solution slightly acidic, add quantitative silver nitrate solution, the chlorine ions become precipitation of silver chloride, ammonium ferric sulfate to indicate
Agents, titrate the excess silver nitrate with ammonium thiocyanate standard, calculated according to the amount of ammonium thiocyanate chlorine content.
4 Reagents
Except as otherwise provided in this section, the reagents used were of analytical grade, laboratory water should be at least in line with GB/T 6682 in three water
Requirements.
4.1 Working Standard reagent sodium chloride (NaCl).
4.2 nitric acid (11).
4.3 silver nitrate solution. c (AgNO3) = 0.1mol/L, 17g of silver nitrate was weighed, dissolved in water, diluted to 1L, stored in a brown
Bottle.
4.4 ammonium ferric sulfate [Fe (NH4) (SO4) 2 · 12H2O] solution. dissolve 40g ammonium ferric sulfate in 100mL water, adding 2mL
Nitric acid, so that the disappearance of brown, store in ground plug small mouth glass bottles, spare.
4.5 chlorine standard solution (1mg/mL). Weigh accurately 1.6487g burning after 550 ℃ ~ 600 ℃ 40min ~ 50min and drying work
As a reference reagent sodium chloride (NaCl) (4.1) in the beaker, dissolved in water and transferred to 1L volumetric flask, dilute to the mark, shake, stored in
Plastic bottle. It can also be GB/T 601 and GB/T 602 preparation, or direct use of certified reference materials.
4.6 ammonium thiocyanate standard solution [c (NH4CNS) = 0.1mol/L]. formulated with reference to the provisions of GB/T 601 and GB/T 602 standard and
set. Which weighed 7.6g ammonium thiocyanate dissolved in water and diluted to 1L, Appendix A can also be calibrated.
5. Apparatus
5.1 laboratory sample grinder or mortar.
