外文摘要：A new high-efficiency adsorbent (PDA-CaCO3) is fabricated via simple thermal calcination of ostracean shells and chemicalmodification with dopamine. The adsorption capacity for Pb(II) and Cd(II) was 336.32 and 175.48 mg g(-1), respectively. Importantly, it can be easily regenerated by low-cost reagents, and exhibited a high adsorption capacity after multiple adsorption-desorption cycles.
