In this work, a cost-effective, environmentally friendly, and convenient method for synthesizing novel heterogeneous catalyst via modification of polystyrene using tetrazole-copper magnetic complex [Ps@Tet-Cu(II)@Fe3O4] has been successfully developed. The synthesized was analyzed TEM (transmission electron microscopy), HRTEM (high resolution-transmission STEM (scanning transmission FFT (Fast Fourier transform), XRD (X-ray diffraction), FT-IR (Fourier transform-infrared spectroscopy), TG/DTG (Thermogravimetry differential thermogravimetry), ICP-OES (Inductively coupled plasma-optical emission spectrometry), Vibrating sample magnetometer (VSM), EDS (energy dispersive X-ray elemental mapping. N-Sulfonyl-N-aryl tetrazoles were in high yields from N-sulfonyl-N-aryl cyanamides sodium azide Ps@Tet-Cu(II)@Fe3O4 nanocatalyst. can be recycled reused easily multiple times an external magnet without significant loss catalytic activity.

Abstract To entrap the water-insoluble medicine, current innovation provides a cost-effective solution to increasing need for hydrophobic gel. Improving bioavailability of medicine that is poorly soluble begins with entrapping substance. By only switching out monovalent ions divalent ones, researchers hope increase hydrophobicity their material. In this experiment, barium were used instead potassium in iota carrageenan make structural, chemical, and physicochemical changes easier during transformation. Hydrophobicity was determined qualitatively by observing ability trap small oil particles repel water, moreover, quantitative investigation carried using weight loss method determine metal ion water isolation value drug entrapment within core linked The metal’s affinity be 90% after 24 h, but it 67% synthesized gel coating metal, clearly shows had greater protection activity. Furthermore, barium-linked exhibited three times capacity parent gel, successfully encased medication controlled release. study how attached polymer its hydrophilic behavior into one. This new inexpensive way do things. However, up until point, addition substrate functionalization have been utilized. leads plan promise improving hydrocolloid gels hold drugs not dissolve water.
