Abstract

The invention discloses an adsorptive magnetic nano material. The adsorptive magnetic nano material is prepared from, by weight, 0.5-1 part of ammonium molybdate, 1-2 parts of polyvinylpyrrolidone, 80-90 parts of ferrous sulfate heptahydrate, 100-110 parts of ferric chloride hexahydrate, 4-5 parts of graphite powder, 10-18 parts of nano carbon powder, 3-4 parts of sodium nitrate, 27-30 parts of potassium permanganate, 170-200 parts of 96-98% sulfuric acid, 27-30 parts of 28-30% hydrogen peroxide, 0.3-1 part of lauroyl diethanolamide, 1-2 parts of calcium stearate, 0.1-0.2 part of silane coupling agent kh550, 0.1-0.13 part of 8-hydroxyquinoline, 1.7-3 parts of sodium potassium silicate and 0.2-0.4 part of butylmercaptooxo stannane. Since magnetic nano ferroferric oxide particles are introduced into the composite material and loaded on the surface of the composite material, dispersity of ferroferric oxide can be improved, and the problem of difficulty in separation and recovery of traditional adsorbent materials from reaction systems is effectively solved. The adsorptive magnetic nano material has an excellent adsorption performance and can be widely applied to magnetically targeted drug loading, bioseparation and the like.
