6.2 Identification test
6.2.1 Extract fiber from alginate dressing for infrared identification based on
the reference to Annex A. The result shall be substantially the same as or in
between the two spectra of the alginate G infrared absorption spectrum or the
alginate M infrared absorption spectrum.
6.2.2 Weigh 5.0 mg of alginate dressing. Add 5mL of water, 1mL of freshly
prepared 1% of 1,3 dihydroxynaphthalene ethanol solution, 5mL of hydrochloric
acid, boil 3min and cool. Add 5mL of water. Extract with 15 mL of diisopropyl
ether. The dark purple in the upper layer shall be deeper than the blank made
in the same method.
6.2.3 Weigh 0.1g of alginate dressing. Add 5mL of water, boil, the sample shall
not dissolve. Add 2mL of 10% sodium carbonate solution to generate white
precipitate. Perform centrifugation and acidification to generate gelatinous
precipitate.
6.3 Loss on drying
Take 0.5g of alginate dressing. Conduct the test according to Annex VIII L in
Part II of Pharmacopoeia of People's Republic of China (Edition 2010).
6.4 pH test
Cut 1.0g of sample into about 1cm2 pieces. Put into a suitable container. Add
50mL of water. Seal at 37°C ± 1°C to soak 24h. Pour the liquid gently, mix, and
obtain the test solution. Determine the pH of the test solution and blank solution
with a pH meter. The difference of these two shall be inspection results.
6.5 Ignition residue test
Take 1.0g of alginate dressing. Conduct the test according to Annex VIII N
Ignition residue inspection method (500°C~600°C) in Part II of Pharmacopoeia
of People's Republic of China (Edition 2010).
6.6 Heavy metal test
Take residue left under 6.5. Perform according to Annex VIII H Heavy metal
inspection method in Part II of Pharmacopoeia of People's Republic of China
(Edition 2010).
NOTE Add 2mL of acetate buffer (pH3.5). After slight heat dissolution, if there is precipitation,
filtrate it and then move to Nessler colorimetric tube.
6.7 Iron content test
Take 1.0g of alginate dressing. Slow bake at 500°C~600°C till complete
V - EDTA volume consumed in the titration, in milliliters (mL);
M - sample mass, in grams (g).
