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).
