Soybean peroxidase has been shown to be effective in removal of aromatic compounds from wastewater, while the use of additives effectively reduces enzyme concentration requirement, hence overall treatment cost. Enzymatic treatment, an oxidative polymerization, was successful in removal of over 95% of both aniline and o-anisidine. The originality of this study lies in the findings that the additives, sodium dodecyl sulfate (SDS), sodium dodecylbenzenesulfonate (SDBS), Triton X-100, and sodium dodecanoate (SDOD), reduced enzyme concentration requirement, while polyethylene glycol (PEG, average molar mass of 3350 g/mol) had no effect on the required enzyme concentration. In addition, the presence of SDS also enhanced treatment by improving precipitation and color removal. These results are enabling advancement of soybean peroxidase-catalyzed treatment of anilines found in wastewaters as a new sustainable method.

大豆过氧化物酶催化去除水中苯胺的添加剂效应

大豆过氧化物酶已被证明可有效去除废水中的芳香族化合物，而添加剂的使用可有效降低酶浓度要求，从而降低整体处理成本。酶促处理是一种氧化聚合，成功去除了超过 95% 的苯胺和邻茴香胺。本研究的独创性在于发现添加剂十二烷基硫酸钠 (SDS)、十二烷基苯磺酸钠 (SDBS)、Triton X-100 和十二烷酸钠 (SDOD) 降低了酶浓度需求，而聚乙二醇 (PEG，平均3350 g/mol 的摩尔质量）对所需的酶浓度没有影响。此外，SDS 的存在还通过改善沉淀和颜色去除来增强处理。
