摘要 在同一反应条件下测得超声波/零价铁(US/Fe)协同降解五种氯苯类化合物符合准一级反应,降解速率常数(k)呈现一定的规律性:1,2,4-TCB>M-DCB>P-DCB>O-DCBCB>CB。采用偏最小二乘法(PLS)建立氯苯类化合物定量结构-性质相关(QSPR)的数学模型,模型的主成分分析结果表明:在US/Fe体系中,影响氯苯类有机物降解的主要因素分别是物质的氯取代程度,分子极化率及亨利常数。 Coordinate degradation of five chlorophenol compounds with US/Fe under the same reaction conditions met kinetic equation with constant of degradation rate disciplinary. Mathematical model of QSPR was established by partial least squares, and results indicated that molecular polarizability and Henry's law constant are major impact factors for degradation of organic compounds.
