Fabrication of sulfamic acid functionalized magnetic nanoparticles with denderimeric linkers and its application for microextraction purposes, one-pot preparation of pyrans pigments and removal of malachite green

In this research, we stated the fabrication of an innovative sulfamic acid functionalized magnetic nanoparticles (Fe3O4@PAMAM-SO3H) with denderimeric linkers. FT-IR, TEM, XRD, FE-SEM, and TGA methods were carried out to characterize the catalyst. Eventually, The catalytic prowess of the Fe3O4@PAMAM-SO3H was tested to synthesize highly substituted pyrans. The obtained magnetic sorbent was also used to remove malachite green (MG) and magnetic...
