Atkinson, Ariel J.; Armstrong, Mikayla D.; Eskew, John T.; Coronell, Orlando published their research in Journal of Membrane Science in 2021. The article was titled 《Aminoimidazole reduces fouling and improves membrane performance》.Reference of 1H-Imidazol-2-amine The article contains the following contents:
Biofouling is difficult to control and hinders the performance of membranes in all applications but is of particular concern when natural waters are purified. Fouling, via multiple mechanisms (organic-only, biofouling-only, cell-deposition-only, and organic + biofouling), of a com. available membrane (control) and a corresponding membrane coated with an anti-biofouling 2-aminoimidazole (2-AI membrane) was monitored and characterized during the purification of a natural water. Results show that the amount of bacterial cell deposition and organic fouling was not significantly different between control and 2-AI membranes; however, biofilm formation, concurrent or not with other fouling mechanisms, was significantly inhibited (95-98%, p < 0.001) by the 2-AI membrane. The limited biofilm that formed on the 2-AI membrane was weaker (as indicated by the polysaccharide to protein ratio) and thus presumably easier to remove. The conductivity rejection by the 2-AI and control membranes was not significantly different throughout the 75-h experiments, but the rejection of dissolved organic carbon by biofouled (biofouling-only, cell-deposition-only, and organic + biofouling) 2-AI membranes was statistically higher (10-12%, p = 0.003-0.07). When biofouled, the water permeance of the 2-AI membranes decreased significantly less (p < 0.05) over 75 h than that of the control membranes, whether or not other addnl. types of fouling occurred concurrently. Despite the initially lower water permeances of 2-AI membranes (11% lower on average than controls), the 2-AI membranes outperformed the controls (10-11% higher average water permeance) after biofilm formation occurred. Overall, 2-AI membranes fouled less than controls without detriment to water productivity and solute rejection. The experimental process involved the reaction of 1H-Imidazol-2-amine(cas: 7720-39-0Reference of 1H-Imidazol-2-amine)
1H-Imidazol-2-amine(cas: 7720-39-0) belongs to anime. Aniline, ethanolamines, and several other amines are major industrial commodities used in making rubber, dyes, pharmaceuticals, and synthetic resins and fibres and for a host of other applications. Most of the numerous methods for the preparation of amines may be broadly divided into two groups: (1) chemical reduction (replacement of oxygen with hydrogen atoms in the molecule) of members of several other classes of organic nitrogen compounds and (2) reactions of ammonia or amines with organic compounds.Reference of 1H-Imidazol-2-amine
