【Abstract】 Under the microwave,the activated carbon from bamboo shavings was prepared with the phosphoric acid according to orthogonal tests.The optimum conditions were obtained.The results of the experiment showed that the bamboo shavings could be producted good activated carbon by the method of microwave_phosphoric acid.The iodine number reached 836 mg·g -1 The decolorizing capacity of metylene blue reached 13 mL·(0 1 g) -1 The decolorizing capacity of caramel adsorption reached 113%.The addition of sulfuric acid or hydrogen peroxide could also significantly improve its adsorb function.更多还原
