Abstract: A method for preparing a solid amine adsorbent of CO2 includes introducing a gas mixture containing 10 vol. % to 50 vol. % of CO2 is introduced into a sodium aluminate solution having a concentration in a range of 10 g/L to 100 g/L at room temperature to obtain a reaction solution. This occurs continuously until a pH value of the reaction solution is lowered to 9.5 to 9.8 to obtain a product solution containing a precipitate. The precipitate is filtered and washed. The filtered and washed precipitate is mixed with an organic alcohol at a mass ratio of 1:5 to 1:30 to obtain a suspension. The suspension is heated to an azeotropic point of water and the organic alcohol, and evaporated, boiled, and refluxed to obtain pore-enlarged pseudo boehmite. This is calcined to obtain aluminum oxide powder. The aluminum oxide powder is impregnated in an organic amine solution and dried.

Abstract: The present disclosure relates to the technical field of molecular diagnosis, and particularly, to a microsphere formulation for nucleic acid amplification, an amplification method, and use in joint detection. The disclosed microsphere formulation can be stored for a long duration at 2-8° C. When the microsphere preparation is used, no solvent is additionally added, and the microsphere formulation is directly mixed with a sample to be detected. On the premise that the concentration of an original system is not changed, the template content in the system can be remarkably improved, so that the detection sensitivity is improved. By using the microsphere formulation in recombinase polymerase amplification (RPA), recombinase-aided amplification (RAA), or a double or multiple detection formed by combining a second reaction on the basis of RPA or RAA, the sensitivity can be remarkably improved, and meanwhile, the amplification specificity is ensured.
