Embodiment 1
[0016] (1) 0.03g of superparamagnetic 500nm NiFe 2 o 4 The nano-microspheres were ultrasonically dispersed into 5ml 1M HCl solution for pretreatment, the magnetic particles were fully washed with deionized water, and then ultrasonically dispersed into a mixture of 100g ethanol, 30g deionized water and 1g concentrated ammonia water. Subsequently, 1.0 g TEOS was added and stirred for 12 h, and finally the product was separated by a magnet, washed with water and ethanol and dispersed into deionized water to obtain a stable dispersion (4.0 wt%) for later use.
[0017] (2) 5.0g of NiFe prepared above 2 o 4 @SiO 2 Microsphere dispersion and 1.0g polydimethyldiallylammonium chloride (PDDA) (Mw=20000g / mol) 1% aqueous solution are mixed, and PDDA is adsorbed on NiFe 2 o 4 @SiO 2 surface. Washing PDDA-adsorbed NiFe with 2.0% ammonia solution 2 o 4 @SiO 2 The microspheres were separated by a magnet, and after repeated 4 times, the NiFe adsorbed PDDA 2 o 4 @SiO 2 The microsph...
