Computed Properties of C6H9N. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2,4-Dimethyl-1H-pyrrole, is researched, Molecular C6H9N, CAS is 625-82-1, about Chitosan based macromolecular probes for the selective detection and removal of Fe3+ ion.
Chitosan has been widely used due to its biodegradable, cost-effective and environmentally friendly properties. Modification of chitosan attracts much attention as promising methods to detect and remove organic and inorganic pollutants. In this work, chitosan-based macromol. probes were designed and synthesized. The probes can detect Fe3+ in the presence of other metal ions. The detection mechanism is investigated as well. The prob′s fluorescence quenching upon the addition of Fe3+ ion could be ascribed to the complexation between the electron-deficient ion Fe3+ and ′C=N′ (electron-rich group) of fluorescent chitosan probes. What′s more, the obtained fluorescent macromol. probes can be used for the removal of Fe3+ in solution The probes could adsorb the Fe3+ in solution and the removal efficiency can reach as high as 62.0% while the removal efficiency of original chitosan is only 16.0%. μThe probes have good selective detection for Fe3+ and the detection limit reaches 1.2 M.
