工业场地氯化石蜡的检测和化学降解方法的研究
摘 要
SCCPs（短链氯化石蜡）的分子式可以缩写为CxH(2x−y+2)Cly，其中所使用的参数x=10～13，y=1～13，氯化程度约在16%～78%之间。由于氯原子的位置不同、碳链长度以及氯化比例的不同，SCCPs实际上是非常复杂的混合物；常温状态下为无色或淡黄色的黏稠液体，并具有轻微的脂芳香味。SCCPs在水中溶解度为0.49～1260mgmL1。短链氯化石蜡(SCCPs)已经被列入POPs的新增清单，具有POPs所定义的环境持久性、远距离迁移性和生物富集性以及毒性等性质。本文通过整理汇总有关研究文献，得出了氯化石蜡对环境产生负面影响的严重性和我国当前研究成果和环保政策监管的缺乏性。本文利用气相色谱对SCCPs进行检测，并总结出了不同峰面积对应的SCCPs浓度公式，用于推算未知浓度的SCCPs溶液。本文探究了不同种类与不同浓度的氧化剂、活化剂对SCCPs的降解效果，总结出了SCCPs的最适降解条件。

ADATION OF CHLORINATED PARAFFINS IN INDUSTRIAL SITES
ABSTRACT
The molecular formula of SCCPs (short chain chlorinated paraffins) can be abbreviated to CxH(2x−y+2)Cly, where the parameters x=10 ~ 13, y=1 ~ 13, and the degree of chlorination ranges from 16% to 78%. SCCPs are actually very complex mixtures due to changes in the position of chlorine atoms, the chlorination ratio, and the length of the carbon chain. It is a colorless or yellowish viscous liquid at room temperature, with a slight fatty aroma. The solubility of SCCPs in water is 0.49 ~ 1260mgmL1. Short chain chlorinated paraffins (SCCPs) have been added to the additional list of POPs with properties defined as environmental persistence, longrange migration and bioaccumulation, as well as toxicity. This paper summarizes the relevant research literature and concludes the severity of the negative impact of chlorinated paraffins on the environment and the deficiency of the current research results and environmental policy supervision in China. In this paper, SCCPs was detected by gas chromatography, and the SCCPs concentration formula corresponding to different peak areas was summarized, which was used to calculate the SCCPs solution with unknown concentration. In this paper, the degradation effects of different kinds and different concentrations of oxidants and activators on SCCPs were investigated, and the optimum degradation conditions of SCCPs were summarized.
