试验结果表明，反应温度对反应产物中邻苯二酚/对苯二酚的比例和催化剂的活性周期的影响不明显，过氧化氢/苯酚摩尔比对邻苯二酚/对苯二酚的比例的影响较大，提高过氧化氢/苯酚摩尔比会降低邻苯二酚/对苯二酚的比例，缩短催化剂的活性周期。

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.

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.
