炼化回用污水反渗透产生的浓水有机物组成分析

分析炼化回用污水反渗透产生的浓水中有机物组成对研发反渗透浓水达标处理技术意义重大。分别采用固相萃取和固相微萃取两种方法，首先对反渗透浓水中有机物进行富集，再采用气相色谱-质谱联用技术对富集样品进行组成分析，结果表明反渗透浓水中有机物主要由芳香族化合物构成，结合质谱谱库和外标法比对分析，相对含量较高的几种有机物分别为苯及含有不同甲基数量的取代萘等。

ANALYSIS OF ORGANIC MATTERS IN REVERSE OSMOSIS CONCENTRATE OF RECYCLING WASTE WATER IN REFINERY

To study the composition of reverse osmosis concentrate is of great significance to develop waste water processing technique. The organic matters were enriched by using solid phase extraction and solid phase micro-extraction respectively,and then analyzed by GC-MS. The results showed that organic matters in the reverse osmosis concentrate mainly consists of aromatic compounds. Combined with the MS spectrum database and external standard method, several kinds of organic matters are determined. The content of benzene and methyl substituted naphthalenes are higher.
