Abstract
New one pot mesoporous hybrid material containing iron nanoparticles fabricated with chitosan and p-sulfonato dansyl calix[4]arene composite (Fe3O4@Chitosan-pSDCalix) has been susccessfully synthesized. These mesoporous fluorescence iron nanoparticles were applied for the detection and removal of environmentally toxic Hg2+ ion from aqueous media. Different techniques were applied to confirm the preparation of Fe3O4@Chitosan-pSDCalix such as HRTEM, TGA/DTA, FTIR and XRD. Synthesized nanoparticles have average size of 17 nm with pore size of 0.19 nm as revealed from HRTEM images. Fluorescence study follow the photoinduced electron transfer process after addition of Hg2+ in the solution with decrease in intensity. Confocal microscope images were also acquired to confirm the presence of Hg2+ on nanoparticles. Adsorption study suggests that the removal of Hg2+ from aqueous media follows Langmuir adsorption isotherm. These studies suggest the synthesized Fe3O4@Chitosan-pSDCalix is an efficient hybrid material for the detection and removal of Hg2+ ion from aqueous media, and that it can also be used in biomolecules for the detection of toxic metal ions.
