Capacity of Oil Cake Ion Exchanger
[摘要] The soy bean oil cakes and perillar oil cakes are phosphorylated and sulfonated to be used as ion exchangers. There 40-60mesh cations exchanges have bean tested on the capacity of ion exchange, the adsorption and distribution coefficients of several metal ions in various concentrations of binary solution mixture, hydrochloric acid and alcohol. From there experiments, the following results are concluded. The ion exchange capacity of ion exchangers are higher than 4 meq/g. The adsorption of metal ions on ion exchangers are increased generally as pH is increased, especially Co(¥±) on sulfonated soy bean oil cake. The distribution coefficients of various metal ions are decreased as the number of branches of carbon and hydroxyl groups are increased. There show that the stereo-isomerism of alkyl group or attraction of ligand have influenced upon various metal ions. Consequently it is deduced that there ion exchanges from soy bean oil cake and perillar oil cake resemble in properties to current ion exchangers.
