Preparation of Soybean Straw Carbon by Microwave Method
Technology of preparing activated carbon from soybean stalks with ZnCI2 assisted by microwave irradiation was studied. The effects of zinc and soybean straw proportion, soaking time, microwave power and microwave heating time on the yield and adsorption properties of methylene blue were measured and analyzed in order to optimize these operation conditions. It turned out that the proportion of ZnCI2 and soybean straw was 3:1, the microwave power was 600w, the time of microwave heating was 17min; the time of activation was -24 hours. Adsorptive value of the methylene blue is 6.3mL/0.1g, BET surface area was 983.1m2/g and its average diameter was 2.397nm, total pore volume was 0.5892mL/g.
