摘要： Methods and compositions for improving performance of flocculants in an industrial production process. Methods include pH triggered cross-linking reaction between a flocculating agent, such as dextran, and a composition comprising a boronic acid-containing polymer. The pH trigger can be provided by a fluid having a pH of 8 or more. The production process can be a Bayer Process and the fluid is caustic liquor or slurry in the fluid circuit of the Bayer, wherein the reaction time is reduced over conventional methods and the cross-linked dextran composition effectuates improved flocculation of the trihydrate particles.

摘要： The objective of the present invention is to obtain an adsorbent having high adsorption capacity and high strength comprising porous cellulose beads obtained without using an auxiliary material which is highly toxic and corrosive and without a cumbersome and industrially adverse step. The present invention is characterized by immobilizing a ligand onto porous cellulose beads obtained by mixing a cold alkaline aqueous solution and cellulose powder as a raw material to prepare a cellulose dispersion and bringing the cellulose dispersion into contact with a coagulating solvent.
