Wang, Dan published the artcileDegradation of octylphenol polyethoxylates with a long ethoxylate chain using the laccase-mediated systems, Name: Ammonium 2,2′-(hydrazine-1,2-diylidene)bis(3-ethyl-2,3-dihydrobenzo[d]thiazole-6-sulfonate), the publication is Environmental Science and Pollution Research (2021), 28(28), 37781-37792, database is CAplus and MEDLINE.

Alkylphenol polyethoxylates (APEOn) are the second-largest category of com. nonionic surfactants, which are difficult to degrade naturally in the environment. This study examined the degradation of octylphenol polyethoxylate (OPEOn) by laccase and its laccase-mediated systems. The results showed that OPEOn was poorly degraded by laccase alone. 2, 2′-azino-bis [3-ethylbenzothiazoline-6-sulfonic acid] (ABTS), 1-hydroxybenzotriazole (HBT), and 2, 2, 6, 6-tetramethylpiperidine-1-oxyl (TEMPO) were selected as the redox mediators. Exptl. results also indicated that 52.4% of the initial OPEOn amount was degraded by laccase in the presence of TEMPO. The degradation efficiency was analyzed using high-performance liquid chromatog. Furthermore, the structural characteristics of the degradation products were measured using matrix-assisted laser desorption/ionization-time of flight mass spectrometry and NMR spectroscopy, and it could be found that the laccase-TEMPO system could gradually shorten the ethoxylate chain by oxidizing the primary hydroxyl group of OPEOn, thereby degrading the OPEOn of the macromol. into small mols. The maximum of the ion peak distributions of OPEOn decreased from n = 8 finally down to 3. The novel enzymic system introduced by this study will become a promising alternative method for high-efficiency APEOn conversion and had great potential value in wastewater treatment.
