Examples
example 1
[0027] Take 1-2g of acrylonitrile-styrene resin completely dissolved in 50-100mL of acetone, heat to 60 or 65 or 70°C and evaporate until the solution is slightly viscous, add 20g of activated carbon, stir and evaporate at 120 rpm until the acetone is completely volatilized, The acrylonitrile-styrene resin is evenly wrapped on the surface of the activated carbon, and dried at 80°C. Place the dried activated carbon in 100mL of chelating solution prepared by adding 0.8g of copper sulfate and 0.4g of sodium thiosulfate per 100mL of deionized water, 50 or 51 or 53 or 56 or 59 or 63 or 67 Or stir and react at 70°C for 1 hour, pour out the reaction solution, soak and wash in deionized water 3 to 5 times, 100mL each time, to remove the reaction solution remaining on the surface of the activated carbon, and dry to obtain the bactericidal and algae-removing activated carbon.
example 2
[0029] Take 10-20g of acrylonitrile-styrene resin completely dissolved in 500mL of acetone, heat to 57 or 60 or 68°C to evaporate until the solution is slightly viscous, add 200g of activated carbon, stir and evaporate at 120 rpm until the acetone is completely volatilized, and the propylene Nitrile-styrene resin is evenly wrapped on the surface of activated carbon and dried at 80°C. Place the dried activated carbon in 1000mL of chelating solution prepared by adding 0.8g of copper sulfate and 0.4g of sodium thiosulfate per 100mL of deionized water, 50 or 54 or 57 or 60 or 62 or 65 or 68 Or stir and react at 70°C for 1 hour, pour out the reaction solution, soak and wash in deionized water 3 to 5 times, 1000mL each time, to remove the reaction solution remaining on the surface of the activated carbon, and dry to obtain the bactericidal and algae-removing activated carbon.
example 3
[0031] Take 15kg of acrylonitrile-styrene resin and completely dissolve it in a reaction kettle filled with 500L of acetone, heat it to 67 or 70 or 75 or 80°C and distill until the solution is slightly viscous and recover acetone, add 200kg of activated carbon, and stir at 120 rpm Evaporate until the acetone is basically volatilized completely, so that the acrylonitrile-styrene resin is evenly wrapped on the surface of the activated carbon, and dried at 80°C. Place the dried activated carbon in 1000L of chelating solution prepared by adding 0.8g of copper sulfate and 0.4g of sodium thiosulfate per 100mL of deionized water, 50 or 52 or 55 or 58 or 61 or 64 or 67 Or stir and react at 70°C for 1 hour, pour out the reaction solution, soak and wash in deionized water 3 to 5 times, 1000L each time, to remove the reaction solution remaining on the surface of the activated carbon, and dry to obtain the bactericidal and algae-removing activated carbon.
