Dialdehyde 8-aminoquinoline starch (DASQA) was synthesized by the reaction of dialdehyde starch (DAS) and 8-aminoquinoline. It was used to adsorb Zn (II) ions from aqueous solution. DASQA was characterized by element analysis, FT-IR spectra, SEM and BET. The results of FT-IR showed the difference between DAS and DASQA in the spectrum. The adsorption study revealed that 120min and pH 5.0 were the optimal...
