| Abstract: | The highly efficient activated carbon was prepared from Solidago Canadensis,an invasive alien weed,by phosphoric acid activation according to orthogonal test method.The effects of operation parameters such as impregnation ratio(A),phosphoric acid concentration(B),activation temperature(C) and time(D) on the adsorption properties and yield of activated carbons were evaluated.It was indicated that the optimum conditions were as follows: impregnation ratio was 1/3(g/ml),phosphoric acid concentration was 40%,ac... |
