摘要
按照燃香类标准GB/T 26386——2011《燃香类产品安全通用技术条件》和GB/T 26393——2011《燃香类产品有害物质测试方法》中关于TVOC测定法的规定,对市场上随机抽查的25个燃香样品进行检测。针对检测中出现的未知组分权重过多、成分复杂所导致的数据代表性差、检测范围不足的问题,探讨TVOC定义及其在相关标准中的适用范围,剖析外标定量分析法对燃香TVOC的影响因素,研究未知组分的计算问题和数据结果的表示方式,分析TVOC这种半定量手段在现行燃香类标准中应用的局限性及其实际操作的困难性。鉴于国内对于燃香类产品的研究较少,且存在着天然产物标准品匮乏和VOCs污染物限制性指标缺少的现状,从相关学科、领域的角度提出解决现行燃香标准化问题的建议,并从实用性的角度提出TVOC的应用方式。随着香产业的兴盛,亟需加快研究和取得技术突破,以此为今后相关法律的制订和标准的完善提供依据。
According to provisions on the TVOC detecting method in incense standard GB/T 26386 2011 and GB/T 26393 2011, 25 incense samples on the market were randomly selected for testing. As for the problems in the measurement, such as overmuch weight of unknown components, poor data representativeness composition caused by components complexity and insufficient detection range, the TVOC definition and its applicable scope in the related standards were explored. Besides, the influence of TVOC factors on the external standard method for quantitative analysis of incense were analyzed. The calculation of unknown components and the expression of data results were studied. Moreover, the limitation and difficulty in the application of TVOC, as a semi-quantitative method in the current incense standard were analyzed. There were scanty indicators of VOCs, natural reference materials, and fewer researches on the incense products to restrict pollutants in China's Mainland. Some suggestions were proposed to solve the current standardization of incense from the aspects of related disciplines and fields. Additionally, the application mode of TVOC was put forward from the perspective of practicality. As incense industry becomes flourishing, it is urgent to accelerate scientific researches and make technology breakthrough, so as to provide basis for the formulation of relevant laws and perfection of standards in future.
