Testing method
A.1 General Provisions
Unless otherwise specified in this standard, the purity of the reagents used were of analytical grade, standard titration solution used, the impurity determined by standard solution formulation
And products shall GB/T 601, GB/T 602, a predetermined preparation GB/T 603, the test water shall meet the GB/T 6682 in three water gauge
set. The test does not indicate when the solution which is formulated with a solvent, refer to the aqueous solution.
A.2 mass percent of total organic selenium Selenium
A.2.1 Reagents and materials
Ethanol.
A.2.2 Analysis step
Weigh about 1g sample (accurate to 0.001 g of) in 50mL small beaker, was added 25mL of anhydrous ethanol was stirred on a magnetic stirrer
5min, until the sample is thoroughly mixed and allowed to stand overnight. The supernatant was filtered with a filter paper was dried, and the filtrate was collected in a clean dry beaker small
, The water volume to 100mL, 2mL taken as a sample solution, the measurement sample for digestion and the method specified in GB 5009.93.
A.2.3 calculation results
The mass fraction of the total selenium content of organic selenium w1, calculated according to formula (A.1).
w1 = 1-
X1
÷ × 100% (A.1)
Where.
The content of the X1 --- inorganic selenium in the sample, in milligrams per kilogram (mg/kg);
X---- total content of selenium in the sample, in milligrams per kilogram (mg/kg).
The test result to the arithmetic mean of replicates results. Obtained in two independent determination results under repeatability conditions of absolute difference
Is not greater than 15% of the arithmetic mean of the results to a decimal Reserved.
