摘要 采用静态法研究了钴离子在凹凸棒石上的吸附行为。钴离子在凹凸棒石上的吸附受体系pH值、离子强度、固液比、富啡酸(FA)及电解质离子的强烈影响。在研究范围内,离子强度对钴离子在凹凸棒石上吸附的影响明显;富啡酸对钴离子在凹凸棒石上的吸附在高pH值下影响明显;在pH<8时不同电解质对钴离子在凹凸棒石上的吸附影响明显。 The sorption of Co （Ⅱ） on attapulgite was studied by batch technique. The sorption of Co（ Ⅱ ） onto attapulgite was strongly dependent on pH, ionic strength, solid-to- liquid ratio, FA, and electrolyte ion. The results indicate that sorption of Co （Ⅱ） onto attapulgite is influenced by ionic strength obviously. The presence of FA reduces the sorp- tion of Co（ Ⅱ ） at high pH values. The sorption of Co（ Ⅱ） on attapulgite is also influenced by the background electrolyte foreign anions at phi8.
