抄録
Waste seashell (scallop shell) based adsorbent was prepared by mechanochemical reaction with sodium oxalate using ball milling. The oxalate modified seashell based adsorbents (OS) were prepared by varying the molar ratio of calcium and oxalate as 0.5, 1, and 2. Sodium oxalate was used as the aqueous solution in ball milling. Lead ion adsorption was conducted with the prepared adsorbent. The adsorption behavior of lead ion was investigated in terms of adsorption kinetics and adsorption equilibrium. Time course of the amount adsorbed of Pb agreed well with Langmuir rate equation. The adsorption equilibrium relationship of OS adsorbent and Pb agreed well Langmuir adsorption isotherm. As increasing with the molar ratio, the saturated amount adsorbed of Pb increased from 5.45×10-3 to 6.23×10-3 mol/g slightly. Under the present experimental conditions, the maximum equilibrium adsorption was 5.93×10-3 mol/g, which is greater than that reported in the literature.
