摘要
研究了氧化活性炭对Cd(Ⅱ)离子的吸附以及多种表面活性剂对吸附量的影响.发现氧化活性炭对Cd(Ⅱ)离子有较强的吸附作用,外加阴离子表面活性剂能显著提高Cd(Ⅱ)的吸附量,而外加阳离子和非离子表面活性剂则降低Cd(Ⅱ)的吸附量。
:Adsorption of Cd(Ⅱ) ion by activated charcoal
oxidized and effect of various surfactants on the adsorption amount have been investigated.It
was found there exists strong adsorption of Cd(Ⅱ) on activated charcoal oxidized.Addited anion
surfactant (SDS) can increase adsorption amount of Cd(Ⅱ),but Cation Surfactant (CPN) and
nonionic surfactant (OP) can decrease the adsorption amount.Finally,optimum cotitions of
adsorption of Cd(Ⅱ) by activated charcoal oxidized have been advanced.
