Abstract: | "Based on the bond order, fukui indices and other related descriptors, as well as temperature, a new QSAR model was established to predict the rate constant (k(O3)) of VOCs degradation by O(3). 302 logk(O3) values (178-409 K) of 149 VOCs were divided into training set (242 logk(O3)) and test set (60 logk(O3)), respectively, which were used to construct and verify the QSAR model. The optimal model (R(2) = 0.83, q(2) = 0.82, Q(ext)(2) = 0.72) shows that E(HOMO), BO(x) and q(C(-))(n) have a greater influence on the value of logk(O3). In addition, fukui indices and logk(O3) are well correlated. The applicability domains of the current models can be used to predict k(O3) of a wide range of VOCs at different temperatures" |
