AZO偶氮染料檢測 Detection of AZO dyes

偶氮基兩端連接烴基（可以是脂肪族烴基，也可以是苯基等芳烴基）的一類有機化合物。偶氮染料是合成染料中品種*多的一類，**用于多種天然和合成纖維的染色和印花，也用于油漆、塑料、橡膠等的著色。
很多偶氮化合物有致*作用，AZO FREE偶氮控已成為國際紡織品服裝貿易中*重要的品質監控項目一，也是生態紡織品*基本的質量指標之一。
A class of organic compounds in which an azo group is connected to a hydrocarbon group (either an aliphatic hydrocarbon group or an aromatic group such as a phenyl group). Azo dyes are the most variety of synthetic dyes, widely used in a variety of natural and synthetic fibers dyeing and printing, but also used in paint, plastic, rubber and other coloring.
Many AZO compounds have carcinogenic effects, AZO FREE azo control has become the most important quality control project in the international textile and clothing trade, and it is also one of the most basic quality indicators of ecological textiles.

產品詳情

偶氮是國際環保要求的必檢項目之一，檢驗方法有以下兩種：氣相色譜及質譜聯用法（GC-MSD）及高效液相色譜法（HPLC）。標準規定被檢產品中不得含有24種偶氮染料中間體，若檢出其中一種即為不合格產品，其限量為要求如下：

GB 18401-2010中可分解致*芳香胺染料：禁用（限量值≤20mg/kg);

GB 20400-2006中規定可分解有害芳香胺染料：（限量值≤30mg/kg);

REACH(Registration，Evaluation， Authorization and Restriction of Chemicals)Annex 17 entry 43中規定：禁用（限量值≤30mg/kg);

Oeko-Tex Standard 100 Appendix 4 中規定： not used（限量值≤20mg/kg）

日本勞動衛生福利部（MHLW）通過修訂“家用產品有害物質管控法案”，將24種偶氮染料列為有害污染物，并進行管控。(限量值≤30mg/kg）。

涉及測試標準：

ISO 14362-1；

ISO 14362-3;

ISO17234-1/2

EN14362-1/3;

EN14362-3

LFGB §64 BVLB 82.02-15:2017

GB/T 17592

GB/T 23344等等

Azo is one of the required test items for international environmental protection requirements, and there are two test methods: gas chromatography and mass spectrometry (GC-MSD) and high performance liquid chromatography (HPLC). The standard stipulates that the tested product shall not contain 24 kinds of azo dye intermediates, if one of them is detected as unqualified product, its limit is as follows:

Decomposed carcinogenic aromatic amine dyes in GB 18401-2010: prohibited (limited value ≤20mg/kg);

According to GB 20400-2006, harmful aromatic amine dyes can be decomposed: (limited value ≤30mg/kg);

As specified in REACH(Registration, Evaluation, Authorization and Restriction of Chemicals)Annex 17 entry 43: Prohibited (limited value ≤30mg/kg).

As stipulated in Oeko-Tex Standard 100 Appendix 4: not used (limited value ≤20mg/kg)

The Ministry of Labor, Health and Welfare of Japan (MHLW) has revised the "Household Products Harmful Substances Control Act" to list 24 azo dyes as harmful pollutants and control them. (Limited value ≤30mg/kg).
