Six kinds of 1,3,4-oxadiazole-functionalized fibers were prepared to evaluate the adsorption capacity for Hg2+. Finally, a functionalized fiber (PANp-PMODF) with the best adsorption performance was selected for further research. The PANp-PMODF fiber was characterized by IR (IR), elemental anal. (EA), SEM (SEM), X-ray diffraction (XRD), and XPS. The PANp-PMODF shows excellent selectivity for mercury ions in a mixed heavy metal ion solution (Hg2+, Ni2+, Pb2+, Zn2+, Ag+, Co2+, Cr3+, Cu2+, and Cd2+), and it can reduce the concentration of Hg2+ to 44 ppb in the actual sewage, which is of great practical value for the treatment of mercury pollution. Furthermore, the adsorbed Hg2+ can be desorbed completely by dilute HNO3 and the PANp-PMODF can be reused many times with excellent recyclability. In the experiment, the researchers used many compounds, for example, 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2Recommanded Product: 103-74-2)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Recommanded Product: 103-74-2
