Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 30166-2013 "Determination of acrylamide in textiles". Compared with GB/T 30166-2013, except for the structure
In addition to adjustments and editorial modifications, the main technical changes are as follows.
--- Changed the scope of the standard (see Chapter 1, Chapter 1 of the.2013 edition);
--- Deleted formic acid and formic acid solution (see 4.4 and 4.5 of the.2013 edition);
--- Added "N-hydroxymethyl acrylamide standard" and "methacrylamide standard" (see 5.4 and 5.5);
--- Changed the standard stock solution and standard working solution (see 5.6 and 5.7, 4.6 and 4.7 of the.2013 edition);
--- Added analytical balance with a graduation value of 0.01g (see 6.3);
--- Changed the limit of quantification (see 9.1, 8.1 of the.2013 edition);
--- Deleted the recovery rate (see 8.2 of the.2013 edition).

GB/T 6682 Specifications and test methods for water used in analytical laboratories
3 Terms and definitions
There are no terms or definitions that require definition in this document.
4 Principle
The sample was extracted by water shaking, and the extract was filtered and purified, and then the acrylamide compounds in Appendix A were determined by high performance liquid chromatography.
Quantitative analysis was performed by external standard method.
5 Reagents
Unless otherwise specified, all reagents used were of analytical grade.
Grade 3 water as specified in GB/T 6682.
5.1 Methanol. Chromatographic grade.
5.2 Acetonitrile. chromatographic grade.
5.3 Acrylamide standard. purity not less than 99%.
5.4 N-Hydroxymethyl acrylamide standard product. purity not less than 98%.
5.5 Methacrylamide standard. purity not less than 98%.
5.6 Standard stock solution (1000 μg/mL). Accurately weigh appropriate amounts of acrylamide standard (5.3), N-hydroxymethyl acrylamide standard
The standard sample (5.4) and methacrylamide standard (5.5) were dissolved in water to make up to volume, and the standard stock solutions with a mass concentration of 1000 μg/mL were prepared respectively.
Note. The standard stock solution should be stored at 4℃~8℃ away from light and has a validity period of 2 months.
5.7 Standard working solution (10 μg/mL). Accurately transfer 1.0 mL of the standard stock solution (5.6) into a 100 mL volumetric flask and add water.
Dilute to the scale to prepare a mixed standard working solution with a mass concentration of 10 μg/mL.
Note. The standard working solution should be stored at 4℃~8℃ away from light and has a shelf life of 7 days.
