A method for preparing a core-shell structure polymer magnetic nanosphere with a high Cr (VI) adsorption capacity includes: adding Fe3O4 powder into a mixed solution of water and ethanol, dispersing Fe3O4 powder in the solution evenly by ultrasound, sequentially adding resorcinol and formaldehyde into the suspension to adjust a pH, stirring and reacting to obtain Fe3O4@RF evenly dispersed in a chitosan solution, dropwise adding the prepared suspension into a mixed solution of paraffin and span 80, stirring for a period of time, adding a glutaraldehyde aqueous solution, stirring and reacting to obtain a magnetic chitosan nanosphere. The magnetic chitosan nanosphere prepared may be applied to adsorbing Cr (VI) in a water solution. Not only the magnetic chitosan nanospheres prepared has a high adsorption capacity for Cr (VI), but also can be quickly separated by an external magnetic field after adsorption.

An evaporated fuel processing device for processing evaporated fuel generated in a fuel tank includes a hollow case and an elastic adsorption member press-fit in the hollow case. The elastic adsorption member has a rectangular prismatic block shape. The elastic adsorption member includes an air-permeable elastic body and constituent granules of a granular adsorbent material disposed in the air-permeable elastic body. The constituent granules of a granular adsorbent material are configured to adsorb and desorb evaporated fuel.

Use of poly(alkylamine)-derived (PAD) self-supported cross-linked polymeric ammonium salts and ionomer hydrogels for adsorbing and desorbing organic contaminants, specifically per and polyfluoro alkyl substances (PFAS) from water.

Cross-linked polymeric resins from anilines linked together with dithiocarbamate alkyl chains. A process for producing the cross-linked polymeric resins by Mannich-type polycondensation of anilines and diaminoalkanes linked together by an aldehyde and subsequent conversion of one or more amine functionalities to dithiocarbamate moieties. In addition, a method for removing heavy metals, such as Hg(II) from aqueous solution via contacting and treatment with the cross-linked polymeric resins.

A method of manufacturing absorbent material from bird feather includes the steps of selecting an appropriate feather material, perform a pre-treatment for cleaning and sterilizing the feather material, crushing the feather material into a crushed material of a size of 0.1 um˜1 cm, and performing a modification treatment of the crushed material by surface activation to produce an absorbent material. After the crushed feather material is processed by a modification treatment, the material may be used to manufacture an absorbent material having both deodoring and filtering functions for adsorbing metal ions, organic solvents, grease or volatile gases.
