摘要

This paper describes the effect of temperature and initial concentration of H_2O_2, Fe(II), PhNO_2 and dissolved oxygen on the degradation rate of PhNO_2 in homogeneous aqueous solution by 'Fenton-like' reagent (H_2O_2_o>>Fe(II)_o). The oxidation products o-, m- and p-nitrophenol were found as intermediates in the ratio 1:1.3-2.8:1.4-2.7 as compared with PhNO_2 when conversion of the latter was less than 25. This fact suggests that hydroxylation of PhNO_2 was promoted by HO~· radicals. The reaction was investigated in a completely mixed-batch reactor under a wide range of experimental conditions: pH ~3.0; 278-318 K; 1.5
