Effects of (a) chemical impregnation ratio (preparation conditions:
microwave power = 360W; radiation time = 5 min), (b) microwave power (preparation
conditions: chemical impregnation ratio = 0.75; radiation time = 5 min) and (c) radiation
time (preparation conditions: chemical impregnation ratio = 0.75; microwave power =
600W) on the carbon yield and adsorption uptake [102].
