摘要:
尾矿坝的废水中含有大量的Ca2+ ,易与碳酸根离子、氢氧根离子形成淤堵物质,堵塞尾矿坝的排渗管,严重时导致溃坝。为处理废水中的钙离子,以壳聚糖为原料,采用乙二胺四乙酸(EDTA)进行接枝共聚反应,制备了一种离子吸附剂。采用傅里叶变换红外光谱仪对样品进行结构分析,确定了该离子吸附剂含有大量EDTA基团。通过模拟实验和络合滴定实验研究了原料配比、样品用量及吸附时间对吸附量的影响。结果表明,该吸附剂的饱和吸附量达到4.3 mmol/g,有着很好的吸附效果。研究为尾矿坝废水中的Ca2+安全处理提供理论依据。
Abstract:
A large number of calcium ions in the wastewater form blockages with carbonate and hydroxide ions to block the drainage pipe and lead to dam-failure in tailings dam. To remove Ca(II) in wastewater, we prepared a ion adsorbent by grafting copolymerization of ethylenediamineteraacetic acid (EDTA) onto chitosan(CS), and characterized its structures by Fourier transform infrared spectroscopy. The result shows that the new ion adsorbent contains a large number of EDTA groups. The effects of mole ratio of CS to EDTAD, CS-EDTAD dosages and adsorption times on Ca(II) adsorption were determined by simulation experiment and complexometry experiment. The results show that the saturated adsorption of Ca(Ⅱ) reaches 4.3 mmol/g, and the new ion adsorbent has a better adsorption capacity. The study provides a theoretical basis for safe treatment of Ca(II) in wastewater from tailings dam.
