The invention discloses a double
metal loaded
sodium alginate / carboxymethylcellulose double-functional microballoon adsorbing material and a preparation method thereof. The method comprises the following steps: dissolving
sodium alginate and carboxymethylcellulose at a
mass ratio of (5-20) to 1 in deionized water, and stirring so as to obtain 1-3wt% compound colloidal
sol; electronically spraying the compound colloidal
sol into a receiving device containing a 1-20wt%
metal ion solution by using an electronic spraying device, stirring, and filtering to obtain
metal ion doped gel microballoons; and leaching the gel microballoons, then soaking the leached gel microballoons in a 5-25wt%
aluminium chloride solution, stirring to obtain a mixture, adding 0.1-3 parts by volume of a cross-linking agent into the mixture, stirring, filtering, leaching and stoving so as to obtain the double metal loaded
sodium alginate / carboxymethylcellulose double-functional microballoon adsorbing material. The preparation method has the characteristics of being simple, low in cost,
environmentally friendly, and the like; the material prepared by adopting the method disclosed by the invention has the good application prospect in the aspects of
water treatment and the like in fields of
chemical engineering,
agriculture, environment protection and the like.
