Embodiment 1
[0035]In the embodiment of the present invention, a new type of composite material of activated carbon for water purification is composed of the following raw materials in parts by weight: 20 parts of silver-loaded activated carbon, 2 parts of nano-titanium dioxide powder, 1 part of ammonium bicarbonate, and 1 part of Raney nickel , 1 part of sodium sulfide, 5 parts of medical stone, 4 parts of chitin, 10 parts of montmorillonite, 2 parts of calcium aluminate, and 1 part of γ-aminopropyltriethoxysilane. Preparation process, 1) Grinding γ-aminopropyltriethoxysilane, chitin and activated carbon, passing through a 200-mesh sieve to obtain mixture A;
[0036] 2) After mixing medical stone, montmorillonite and Raney nickel, add distilled water 10-12 times the mass of the three, and then perform ultrasonic treatment on it. The ultrasonic treatment conditions are: temperature 58°C, ultrasonic power 500W, ultrasonic treatment Time 60min; Prepare mixture B;
[0037] 3) After mixing na...
