Sorbent materials are described that have enhanced performance in removing chlorine and chloramine, among other toxic compounds. The sorbent materials are formed by a process which includes steps of oxidation, adding a nitrogen-containing compound, and calcining the sorbent. The processes of forming the sorbent materials are also disclosed. The sorbent materials have excellent performance as measured by a chloramine and/or chlorine destruction number, and the sorbents retain a high nitrogen edge concentration. The sorbent materials may also be incorporated into devices such as filter assemblies.

The present invention provides composite material having a porous graphene-based foam matrix and comprising porous inorganic micro-particles and metal oxide nano-particles distributed throughout the foam matrix.

A composition for use in bioseparation. The composition includes a plurality of hollow particles having a siliceous surface. The composition further includes a surface-modifying agent bonded to the hollow particles. The surface-modifying agent includes a binding segment and a reactive segment. The binding segment includes a silyl group and the reactive segment includes a reactive nitrogen group.

A polyelectrolyte coated fly ash is described with a method of making and a method of using for the adsorption of a contaminant from a solution. The polyelectrolyte coated fly ash may be made by treating the oil fly ash with acid, and then contacting the product with a positive polyelectrolyte to create a first polyelectrolyte layer, and then with a negative polyelectrolyte to create a negative polyelectrolyte layer. The resulting polyelectrolyte coated fly ash quickly adsorbs contaminants from solution, and may be cleaned and reused.

A method is provided for strongly immobilizing a ligand by inactivating an excess formyl group. Methods are also provided for immobilizing a ligand on a formyl group-containing insoluble base material, where the ligand has a specific affinity for a target compound and also has an amino group. The methods comprise the steps of mixing the ligand with the formyl group-containing insoluble base material to form an imine, and reducing the imine by using two or more kinds of reducing agents.

A sorbent useful for CO.sub.2 capture is described, including a solid support with CO.sub.2-sorbing amine and ionic liquid thereon. The ionic liquid is catalytically effective to enhance sorbent characteristics such as (i) CO.sub.2 sorption capacity, (ii) CO.sub.2 sorption rate, (iii) CO.sub.2 desorption capacity, (iv) CO.sub.2 desorption rate, and (v) regeneration temperature, in relation to a corresponding sorbent lacking the ionic liquid. In specific implementations, the sorbent is regenerable at temperatures significantly below 100 C., thereby avoiding the need for steam heat desorption and enabling utilization of waste heat or other low energy thermal regeneration sources.

There is described a method of making an adsorbent material comprising mixing first particulate material with a second material, homogenising the mixture of the first and second materials, incorporating an impregnating or coating material capable of carbonisation, and carbonising the mixture. Also described are adsorbent materials manufactured according to said method and the use of such adsorbent materials in the treatment of a contaminated liquid. Further described is a method of removing contaminants from a quantity of contaminated liquid.
