This method comprises the following steps: (i) modifying the inner wall of the chromatography column by implementing the following steps: (a) preparing a polymerizable anchoring composition comprising at least one particular methacrylate monomer, one or more solvents and 2,2-dimethoxy-2-phenylacetophenone, (b) depositing, on the inner wall of the column, the polymerizable anchoring composition prepared in step (a), and (c) polymerizing the polymerizable anchoring composition by irradiation with ultraviolet radiation; (ii) introducing, into the interior volume of the column, a polymerizable monolith synthesis composition comprising first and second particular (meth)acrylate monomers, one or more pore-forming agents and a free-radical polymerization initiator; and (iii) polymerizing the polymerizable monolith synthesis composition. The invention also relates to a method for producing a chromatography column comprising such a monolithic stationary phase and to a chromatographic separation method using such a column. |

Method of preparing superabsorbent polymer
A method of preparing a superabsorbent polymer, which enables the preparation of the superabsorbent polymer exhibiting an improved absorption rate while maintaining excellent absorption performances is provided. The method of preparing the superabsorbent polymer includes carrying out a crosslinking polymerization of a water-soluble ethylene-based unsaturated monomer having acidic groups which are at least partially neutralized, in the presence of an internal crosslinking agent having a predetermined chemical structure to form a water-containing gel polymer, gel-pulverizing the water-containing gel polymer, drying, pulverizing, and size-sorting the gel-pulverized water-containing gel polymer to form a base polymer powder, and carrying out a surface crosslinking of the base polymer powder by a heat treatment in the presence of a surface crosslinking agent, wherein the gel-pulverizing is carried out by extruding the water-containing gel polymer through a porous plate having a plurality of holes using a screw extruder mounted inside a cylindrical pulverizer under a condition that a chopping index is 28 (/s) or more. |

Process for producing a calcium phosphate reactant, reactant obtained and use thereof in the purification of liquid effluents
A process for producing a calcium phosphate reactant, according to which: in a first step, use is made of a source of calcium and a source of phosphate ions in water, in a molar ratio that is adjusted so as to obtain a Ca/P molar ratio of between 0.5 and 1.6, and the source of calcium is reacted with the phosphate ions at a pH of between 2 and 8, in order to obtain a suspension (A) of calcium phosphate, and in a second step, added to the suspension (A) are an alkaline compound comprising hydroxide ions in order to set a pH of more than 8 and an additional source of calcium in order to obtain a suspension (B) of calcium phosphate reactant having a Ca/P molar ratio of more than 1.6. A calcium phosphate reactant obtainable by such a process. |
