Abstract: A method for producing a modified sawdust sorbent. The method involves sulfonating sawdust with sulfuric acid and oxidizing the sulfonated sawdust with hydrogen peroxide. The method yields a modified sawdust sorbent containing sulfonated and oxidized cellulose. The modified sawdust sorbent has a higher surface area, higher organic dye adsorption capacity, and more rapid organic dye adsorption rate than unmodified sawdust. A method for organic dye removal from water includes using the modified sawdust sorbent to absorb dyes from water.

Abstract: Provided is a manufacturing method for monolithic structure that is a porous body formed of polysaccharide being a naturally-occurring polymer, has continuous pores with an average pore diameter suitable for biomolecule separation, and allows formation into arbitrary shape. The polysaccharide monolithic structure is manufactured by a method including a first step of obtaining a polysaccharide solution by dissolving polysaccharide into a mixed solvent of a first component and a second component at temperature lower than a boiling point of the mixed solvent, and a second step of obtaining polysaccharide monolithic structure by cooling the polysaccharide solution, wherein the first component is a solvent selected from lactate, and the second component is a solvent selected from water, lower alcohol, and a combination thereof. The monolithic structure obtained is a porous body having continuous pores with an average pore diameter of 0.01 to 20.0 micrometers, and a thickness of 100 micrometers or more.

Abstract: A method of separating a metal organic framework (MOF) from a solution and associated apparatus. The method comprises: providing a MOF containing solution; contacting the MOF containing solution with an acoustic reflector surface such that, any high frequency ultrasound applied within the MOF containing solution reflects off the acoustic reflector surface; and applying a high frequency ultrasound of at least 20 kHz to the MOF containing solution. The MOF material is substantially separated from solution as aggregated sediment that settles out of solution.
