Adsorption Behavior of Copper Ion on Cellulose-Triacetate Polymer Containing α-Hydroxyoxime Compounds

抄録

A series of α-hydroxyoximes were synthesized and characterized. A new type of the adsorbent, cellulose triacetate (TAC) powder containing α-hydroxyoximes, has been prepared by dissolving cellulose triacetate with α-hydroxyoxime in 1, 2-dichloromethane, and pouring the mixture in hot water. The adsorption aspects of the TAC powder for the copper(II) ion from dilute aqueous solution were investigated for five kinds of α-hydroxyoximes. TAC powder containing α-hydroxyoximes was found to be useful for the preconcentration or the selective trapping of specific metal ions such as copper(II), nickel(II), at a low concentration level.
