3 Terms and Definitions
This document does not have terms and definitions that need to be defined.
4 principles
Dissolve and remove silk from the mixture of known dry mass with hydrochloric acid, collect the residue, wash, dry and weigh; use the corrected mass
The amount is calculated as the dry mass fraction of the mixture. The mass fraction of silk was obtained from the difference.
5 reagents
5.1 Use the reagents specified in GB/T 2910.1 and 5.2 and 5.3 of this document.
5.2 Hydrochloric acid solution (mass fraction is 35%). Dissolve concentrated hydrochloric acid in water and adjust the solution density to 1.177 g/mL~1.179 g/mL
(25°C). The concentration range of hydrochloric acid solution is allowed to be between 34% and 36% (mass fraction).
Warning. This reagent is highly volatile and will cause harm to the human body. It should be used in a fume hood and complete protection measures should be taken.
Note. The reagent should not be stored for a long time, it should be prepared and used immediately.
5.3 Dilute ammonia solution. Dilute 80 mL of ammonia water (density ρ=0.880 g/mL) to 1 L with water.
6 devices
6.1 Use the equipment specified in GB/T 2910.1 and 6.2, 6.3 and 6.4 of this document.
6.2 Erlenmeyer flask with stopper. the capacity is not less than 250 mL.
6.3 Water bath oscillator. the oscillation frequency can be adjusted from 50 times/min to 100 times/min, and the temperature can be adjusted in the range of ambient temperature to 99.9 ℃.
