Study on preparation of rice husk-based activated carbon and its adsorption of methylene blue
稻壳基活性炭的制备及其对亚甲基蓝吸附的研究

Activated carbon was prepared from rice husk by using K2CO3 and H3PO4,and the two types of activated carbon prepared by these two chemicals have specific surface areas of 1 312 m2/g and 682 m2/g respectively.Activated carbon with developed pore structures was used to adsorb methylene blue after being characterized by scanning electron microscope(SEM) and X-ray diffraction(XRD).Results show that the activated carbon prepared by K2CO3 activation has more microporous structures.The removal rate of methylene bl...
