An objective of the present disclosure is to provide an adsorption material that has a carrier material with retained physical strength, and efficiently adsorbs an immunosuppressive protein. The present disclosure provides an adsorption material for immunosuppressive protein. The adsorption material includes a water-insoluble carrier to which at least one nitrogen-containing compound selected from a polyamine represented by a predetermined formula and aliphatic amines represented by predetermined formulae is bound. A total content of amino groups on the water-insoluble carrier is more than 0 μmol and 2500 μmol or less per 1 g, and a content of primary amino groups on the water-insoluble carrier is 450 μmol or less per 1 g.

A composition for treating water including an organic soil amendment and having ions bound thereto is beneficial to aid in the removal of aqueous contaminants, such as phosphate, other phosphorus containing compounds, arsenic, arsenic containing compounds, fluorides, and PFAS from water. In these compositions the ions include rare earth cations, iron cations, and mixtures thereof. There are also methods for making these soil amendment compositions, as well as methods for using these compositions to effectively remove contaminants from water.

Purification devices and methods remove perfluorinated compounds (PFCs) from PFC-contaminated water using temperature swing adsorption and desorption.

The present invention is to provide a novel adsorbent which is low in cost, has versatility and high adsorption ability. Specifically, the present invention is to provide an adsorbent of a specific metal element containing a metal salt of a cyanometallic acid, a method for producing the same, and a method for removing the ion of the element that is the target of adsorption using such an adsorbent.

Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.
