The research results were published in《Chemical Engineering Journal (Amsterdam, Netherlands)》 in 2021.Reference of 2-Hexyl-1-decanol The article conveys some information:
Potassium permanganate (KMnO4), one typical strong oxidant, is used extensively in various applications. However, its impact on anaerobic fermentation of waste activated sludge is unknown. This paper therefore aims to investigate its effect on generation of short-chain fatty acids (SCFAs) and qualities of fermentation liquor and fermented solid sludge. Exptl. results showed that when KMnO4 increased from 0 to 0.1 g/TSS, the highest SCFAs production enhanced from 33.9 to 251.8 mg COD/g VSS. The mechanism anal. revealed that KMnO4 addition increased the disintegration of sludge cells and the degradation of substantial recalcitrant organics in sludge such as humus and lignocellulose, thereby provided more substances for SCFAs generation. UV absorption spectroscopy anal. showed that KMnO4 addition destroyed unsaturated conjugated bonds and decreased organics aromaticity, thereby promoting humus and lignocellulose degradation In addition, the sludge mixture was separated into liquid and solid fraction after anaerobic fermentation, and the components in fermentation liquid and solid sludge were tested. It was found that the addition of KMnO4 effectively reduced the categories and total detected frequency of refractory organic pollutants in fermentation liquid, which improved the quality of the produced SCFAs. KMnO4 addition also increased the inactivation of fecal coliforms and degradation of emerging contaminants in fermented sludge, which were helpful to its final disposal. And 2-Hexyl-1-decanol (cas: 2425-77-6) was used in the research process.
2-Hexyl-1-decanol(cas: 2425-77-6) has been shown to inhibit the growth of b16 mouse melanoma cells, suggesting it may be useful for treating skin cancer.Reference of 2-Hexyl-1-decanol This fatty acid also has transport properties and can form hydrogen bonds with other molecules.
