Eggshell waste was successfully used for the removal of heavy metal ions from model solutions. The effect of ball milling on the structure and adsorption ability of eggshell (ES) and its membrane (ESM) was investigated, with the conclusion that milling is benefitial only for the ES. The adsorption experiments showed that the ESM is a selective adsorbent, as the adsorption ability toward different ions decreased in the following order: Ag(I) > Cd(II) > Zn(II). The obtained Qm values for Ag(I) adsorption on the ESM and ES were 52.9 and 55.7 mg g(-1), respectively. The potential industrial application of ES was also demonstrated by successful removal of Ag(I) from the technological waste.
蛋壳废弃物成功用于从模拟溶液中去除重金属离子。研究了球磨对蛋壳（ES）及其膜（ESM）结构和吸附能力的影响，得出球磨仅对ES有益的结论。吸附实验表明，ESM是一种选择性吸附剂，因为其对不同离子的吸附能力按以下顺序降低：Ag(I) > Cd(II) > Zn(II)。在ESM和ES上吸附Ag(I)得到的Qm值分别为52.9和55.7 mg g(-1)。从工艺废料中成功去除Ag(I)也证明了ES在工业上的潜在应用。
