Linear Free Energy Relationships for the Biotic and Abiotic Reduction of Nitroaromatic Compounds

摘要: Nitroaromatic compounds (NACs) are ubiquitous environmental contaminants that susceptible to biological and abiotic reduction. Prior works have found for the reduction of NACs, logarithm NACs’ rate constants correlate with one-electron potential values NACs (EH,NAC1) according linear free energy relationships (LFERs). Here, we extend application LFERs bioreduction by bioreduced (and pasteurized) iron-bearing clay minerals. A correlation (R2 = 0.96) was between (kobs) EH,NAC1 values. The LFER slope log kobs versus EH,NAC1/(2.303RT/F) close one (0.97), which implied first electron transfer NAC rate-limiting step bioreduction. were also established minerals (montmorillonite SWy-2 nontronite NAu-2). second-order reductio...
