对苯二酚

It has been observed that pyrocatechol and m-phenylenediamin can sensitively inhibit the discoloration of neutral red oxidation by the H2O2 and in the presence of catalyzer Fe in dilute sulfuric acid solution but the inhibitory effects of two organic compounds can not be added. Based on this research, the advantages of artificial neural network were adopted to handle the experimental data and a new inhibitory kinetic spectrophotometry of simultaneous determination for pyrocatechol and m-phenylenediamin with artificial neural networks was established.

C. I. Reactive blue KN-R, Alizarin brilliant green G and Hostlam blue R could not be degraded by Zoogloea HP3. Furthermore, ABAS degradation was regressed under the exisitence of the above dyes. 1-Aminoanthraquinone-2sulfonic sodium, 1, 4-dihydroxylanthraquinone-2-sulfonic sodium, 1, 4, 5, 8tetrahydroxylanthraquinone, anthraquinone, aniline, phenol, catechol and ophthalic acid could be degraded by Zoogloea HP3. Aniline was the most degradable substrate among ABAS, aniline, phenol, catechol and o-phthalic acid. However, benzenesulfonic sodium and p-amino benzenesulfonic sodium were not degraded by it.
