Preparation method of hydrophilic porous formed activated carbon
The invention relates to the field of functional materials, and especially relates to a preparation method of hydrophilic porous formed activated carbon. The preparation method of the hydrophilic porous formed activated carbon comprises the following steps: preparing a proper concentration of an aqueous solution of a water-soluble hydroxy polymer; weighing a certain amount of the water-soluble hydroxy polymer, dissolving the certain amount of the water-soluble hydroxy polymer in distilled water, swelling and dissolving, and cooling; adding 2wt% of an aqueous solution of NaOH to alkalize, and adding a proper amount of activated carbon into the above obtained glue system; adding a proper amount of a cross-linking agent chloropropylene oxide, and controlling a mass ratio of the water-soluble hydroxy polymer to chloropropylene oxide; adding a foaming agent ammonium bicarbonate, and uniformly stirring; reacting under stirring in a warm water bath, and neutralizing after the reaction to make the pH be 7; and pouring the above obtained activated carbon mixed solution into a die, and drying in a 110DEG C oven. The preparation method has the advantages of simple process and convenient operation, and the formed activated carbon obtained in the invention has the advantages of water resistance, acid and alkali resistance, and high cost performance.
