　　【化工仪器网政策标准】在世界各国，关注染料生产、强调安全环保已成为当务之急，美国、欧洲、日本已建立了研究染料生态安全和毒理的机构，专门了解和研究染料对人类健康与环境的影响。而多环芳烃具有致癌风险，染料产品中若含有该物质，会危害呼吸道和皮肤继而引起急性或慢性伤害，故而我国亟需多环芳烃检测方法标准出台。

　　通过对国内外相关标准和法规及产品的检测手段的分析，遵循技术先进、安全适用的原则，江苏吉华化工有限公司、沈阳化工研究院有限公司等单位吸收了国内外相关标准的研究成果，结合了近几年国内染料产品的实际质量状况和发展趋势，确定相应的试验方法，制订了《染料产品中多环芳烃的测定》。该标准已经编制完成，目前正面向社会征求意见。

　　阅读标准征求意见稿后可知，《染料产品中多环芳烃的测定》引用了《数值修约规则与极限数值的表示和判定》，规定了采用气相色谱-质谱法测定染料产品中18种多环芳烃残留量的方法。而标准中规定的测定范围也较广，适用于各种类别染料产品中多环芳烃的测定。

　　使用气质联用方法测定多环芳烃需要用到的仪器设备有气相色谱-质谱联用仪、色谱柱、分析天平、超声波发生器、提取器、离心机和固相萃取装置。其步骤为标准溶液的配制、试样溶液的制备、分析，为确保结果可信，试验中还需按照与试样溶液制备的相同步骤制备空白试样。经过多番试验后得知，采用标准加入法，在1g染料试样中加入适量多环芳烃标准溶液，加标浓度为10mg/kg，测得的多环芳烃回收率应在70%~120%，萘的回收率在60%~120%。

　　随着该标准的发布与实施，生产企业对染料产品的质量控制将更加严格，会通过对生产工艺进行调整、改造，不断提高产品质量，同时降低原材料的消耗，继而大幅度增加企业的经济效益并减少环境污染和资源浪费。为此，希望相关单位在仔细研核后，提出相关建设性意见。
