The invention provides a method used for high efficiency adsorbing of
heavy metals with a functionalized magnetic material rich in
thio amino groups, relates to preparation of a
thio amino functional group modified hyperbranched
polymer magnetic material, belongs to the field of functional material and heavy
metal adsorption, and more specifically relates to removing of Pb2+, Cu2+, Cd2+, and Hg2+ in aqueous solutions with a hyperbranched
polymer functionalized magnetic compound material with terminal amino groups modified with
sulfur-containing
chelation groups via static adsorption. The terminal amino group hyperbranched
polymer contains a
high molecular weight polymer with a network ball similar three-dimensional structure which is capable of increasing the density of surface functional groups. Compared with linear polymers, the polymer with the hyperbranched structures possesses following advantages: molecular chain entanglement is not easily caused,
solubility is high,
viscosity is low, the molecular structure is spherical, the interior of the polymer is provided with a large amounts of cavities, and the
molecular surfaces possess a large number of reaction active sites, so that it is benefit for introduction of certain
chelation groups, and the polymer is capable of increasing adsorbing efficiency in application in adsorption field. The polymer is capable of removing heavy
metal ions such as Pb2+, Cu2+, Cd2+, and Hg2+ in aqueous solutions completely; the adsorbing materials are widely available; cost is low; operation is simple; removing effect is achieved quickly; and efficiency, selectivity, and adsorption capacity are high.
