- Abstract:
- With APTES as a modifer, the modified ATP was successfully prepared. And the adsorption of Pb(II) from aqueous solution by modified ATP was studied. The physical structure and chemical composition of raw ATP, purified ATP and modified ATP were characterized by SEM、XRD、BET、FTIR and TGA, respectively. The effects of contact time、the dosage of adsorbent、temperature and initial concentration on the adsorption property for Pb(II) were investigated through single factor static experments. The results showed that the equilibrium adsorption capacity of Pb(II) was 241.4mg•g-1 under the following conditions:contact time 80 min、the dosage of adsorbent 0.35g•L-1、temperature 35ºc、 ph 6 and initial concentration 100mg•L-1.
