摘要： A method of treating contaminated water, such as wastewater, with carboxylated cellulose to remove ammonium and nitrogen-containing impurities is claimed. Carboxylated cellulose extracted by nitro-oxidation has negatively-charged functionality and forms an aggregate when exposed to positively-charged impurities in contaminated water. The aggregate, nitrogen-containing impurities, and by-products from the nitro-oxidation process can be isolated to provide a fertilizer or fertilizer component.

摘要： A separating column (12) for hippuric acid analysis is filled with a filler in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to a silica matrix. By using such a filler for the separating column (12) in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to the silica matrix, hippuric acid, o-methyl hippuric acid, m-methyl hippuric acid, p-methyl hippuric acid, and mandelic acid can be separated without using a mobile phase containing cyclodextrin.

摘要： A chromogenic absorbent material for an animal litter includes an oxidizing agent responsive to peroxidatic/pseudoperoxidatic activity in an animal excretion or a first catalytic compound generating the oxidizing agent in situ. The material also includes a chromogenic indicator being chromogenically responsive to the oxidizing activity of the oxidizing agent, and an absorptive material which is porous, for absorbing the animal excretion. The absorptive material includes a water-absorbing polysaccharide providing absorptive properties to the chromogenic absorbent material; and may also include a second polysaccharide and a superabsorbent polymer. The material may be obtained in the form of particles having a low density and a high porosity, and is usable in conjunction with an animal litter for detecting various diseases in animals.

摘要： A composition and method for the removal of water from a water-containing hydrocarbon stream, and a method for the production of a metal/water-soluble polymer composite are provided. The composite includes a water-soluble polymer, such as guar gum, and a metal salt, such as aluminum nitrate or copper sulfate. The ratio of the metal salt to the water-soluble polymer is in the range from about 1:1 to about 5:1 by mass. The water-soluble polymer and the metal salt form a crosslinked material. The method for producing the metal/water-soluble polymer composite includes mixing a non-crosslinked water-soluble polymer with a metal salt and water to form a paste. The paste is then dried.

摘要： A sodium alginate-gelatin based biochar multivariate composite material, a preparation method therefor and a method for removing cadmium in water body are provided and relate to the technical field of biochar adsorbent materials. The sodium alginate-gelatin based biochar multivariate composite material has a high and stable removal efficiency for cadmium divalent cation (Cd2+) in a potential of hydrogen (pH) range of 4-7 in the water body, with a maximum adsorption capacity of 86.25 (milligrams per gram) mg/g. The composite material of the disclosure has good recyclability. After five regeneration tests, the adsorption capacity of the composite material for Cd2+ can still reach 70% of the initial adsorption capacity. The preparation method of the disclosure has simple process, easy control, low manufacturing cost, and is suitable for large-scale production and application.
