Abstract: The present invention relates to a method for preparing a super absorbent polymer. The method for preparing a super absorbent polymer according to the present invention comprises the steps of: preparing a hydrogel polymer by carrying out a thermal polymerization or a photopolymerization of a monomer composition including a water-soluble ethylene-based unsaturated monomer and a polymerization initiator; drying the hydrogel polymer; pulverizing the dried polymer; mixing the pulverized polymer with a surface crosslinking agent and a polymer particle having a core-shell structure; and carrying out a surface crosslinking reaction. According to the present invention, the super absorbent polymer having improved permeability can be obtained by adding the polymer particle during surface crosslinking.

Abstract: A treatment media, system, and method are disclosed which combines adsorptive capacity of a carbon media (e.g., biochar) with chemical treatment characteristics of a red mud substance, e.g., to remove metals and/or other contaminants from waters. The treatment media may also improve biological conditions of affected soils. In an example treatment method, a lignin based material is thermo-chemically decomposed to have a large weight fraction of carbon (e.g., the biochar), and an ore is processed to yield aluminum oxide comprising a variety of iron oxides and having high alkalinity in slurry (e.g., the red mud). The thermo-chemically decomposed lignin based material is combined with the mud material.

Abstract: The present invention relates to a method for preparing a solid amine gas adsorption material. The method synthesizes a porous solid amine gas adsorption material that loads organic amine evenly. In the method, a certain amount of acidic gas is introduced while organic amine molecules are introduced into a silicate solution as template agents, which not only makes sizes of SiO2 pore channels homogeneous, but also makes organic amine molecules highly evenly distributed on a surface of SiO2. In addition, the acidic gas protects —NH2 groups of organic amine, and avoids —NH2 adhesion inactivation due to hydrogen bonding during the synthesis process of the material. The present invention also relates to a method for preparing a solid amine gas adsorption material after obtaining a silicate solution from fly ash. The solid amine gas adsorption material prepared has more stable and effective gas adsorption performance.
