In the present study, novel antibody complex was synthesized from polyamide-amine dendrimer immobilized tetracycline(TC) antibody with the encapsulation of magnetic Fe3O4 nanoparticles. As-prepared magnetic Fe3O4-PAMAM-antibody complexes were characterized by different techniques such as Fourier transform infrared(FT-IR), X-ray diffraction(XRD), Nuclear magnetic resonance(NMR)and ultraviolet(UV) analysis spectra. The prepared antibody complexes exhibited high adsorption properties for TC from aqueous solutions. These results suggest that the antibody complex expects to be a potential candidate for the wastewater treatment.展开更多

In addition, these materials are not sensitive enough to low concentrations of antibiotics. Here we show that a sensitive and specific material was developed by the preparation of magnetic Fe_(3)O_(4)-PAMAM-antibody complexes for treating tetracycline. The prepared antibody complexes can specifically treat tetracycline from aqueous solutions and the tetracycline removal ability by adsorption was also investigated. Controlled experiments were carried out with the effects of solution pH, temperature, and initial concentration of the tetracycline. The tetracycline was completely removed within 35 min at room temperature 30 ℃ with the maximum removal rate of almost 100%. Therefore, this material for specifically combining antigen and antibody to treat tetracycline indicated good application prospects for the waste water treatment.展开更多
