[0021] First, place the three-necked flask in an ice-water bath at 0°C, and mix the acrylic acid monomer and deionized water in the three-necked flask at a mass ratio of 1:1, stir and mix, and vent the air with nitrogen, and then under a nitrogen atmosphere, Place the three-necked flask at room temperature, dropwise add 30% sodium hydroxide solution into the three-necked flask, adjust the pH to 6.5, and keep stirring for 10 minutes to prepare the matrix mixture, which is weighed in parts by weight 45 parts of matrix mixture, 10 parts of 0.5% hydrogen peroxide, 10 parts of vitamin C and 25 parts of N,N'-methylenebisacrylamine were placed in a three-necked flask, heated in a water bath at 45°C for 3 hours, and then heated in a water bath After completion, the filter residue was filtered and vacuum freeze-dried to prepare a porous water-absorbing resin. Then, according to the mass ratio of 1:1:10, nano-iron powder, nano-aluminum powder and porous water-absorbing resin were placed ...
