研究了水蒸汽活化和化学活化两类活性炭纤维(ACF)对水溶液中单组分亚甲基蓝和Ag(NH3)2+以及两者并存时的吸附特征.ACF对水溶液中亚甲基益的吸附量主要取决于其表面积和孔分布.ACF对Ag+的还原—吸附能力则主要取决其表面的化学性质.相同条件下,化学活化的ACF对银离子的还原吸附量(300mg·g-1)比尔蒸汽活化的ACF的还原—吸附量(100mg·g-1)高.溶液中亚甲基益的存在显著改变了水蒸汽活化ACF对银离子的还原—吸附能力,使其对水中银离子的还原吸附量达600mg·g-1以上.
Single component adsorption and coadsorption behavior of Ag(NH3); and methylene blue on two kinds of ACFs, aCtivated with steam and ZnCl2 respectively, were studied. The adsorption of methylene blue on these two kinds of ACFs could be described with Langm
