摘要

研究了阴离子树脂对氰化废水中重金属(Cu、Zn和Fe)的去除效果。采用某氰化浸出厂出水(铜135 mg/L、锌196 mg/L、铁5.3 mg/L)进行试验。比较了Dowex 21K XLT、Purolite A193和Purolite S992三种不同树脂对铜和锌的吸附性能(24 h)，发现Dowex 21K XLT是最有效的树脂。采用不同剂量Dowex 21K XLT (1-5-10-20 g/L)处理24 h的动力学实验，观察到1 h后铜的吸附回收率发生显著变化。小时。5 g/L树脂对铜的吸附速度快，1 h后对铜的吸附曲线没有明显变化，吸附率为57%。随着树脂用量从5 g/L增加到10 g/L，铜的吸附性提高到94%。在测试的最高树脂用量(20 g/L)下，铜几乎完全去除。同样，高树脂剂量(≥10 g/L)似乎需要实现锌和铁的高吸附回收率(≥97%)。研究结果表明，使用Dowex 21K XLT阴离子树脂可以很容易地去除氰化废水中的重金属(Cu、Zn和Fe)。ATIK SİYANÜR ÇÖZELTİLERİNDEN ANYONİK REÇİNELER İLE AĞIR METALLERİN ADSORPSİYONU阴离子树脂对废氰化物溶液中重金属的吸附Fırat Ahlatcıa，*， Elif Yılmaza，**， Ersin Y.

ATIK SİYANÜR ÇÖZELTİLERİNDEN ANYONİK REÇİNELER İLE AĞIR METALLERİN ADSORPSİYONU

In this study, removal of heavy metals (Cu, Zn and Fe) from cyanidation effluents using anionic resins was investigated. The effluent obtained (135 mg/L Cu, 196 mg/L Zn and 5.3 mg/L Fe) from a cyanide leach plant was used in tests. Cu and Zn adsorption performances (24 h.) of three different resins (Dowex 21K XLT, Purolite A193 and Purolite S992) were compared and Dowex 21K XLT was found to be the most effective resin. Kinetic tests at different dosages (1-5-10-20 g/L) of Dowex 21K XLT were carried out for 24 h. significant changes were observed to copper adsorption recoveries after 1. hour. Copper adsorption was fast in that no significant change in adsorption profile was observed after 1 h. Fifty seven percent of copper was adsorbed at 5 g/L resins. Adsorption of copper increased to 94% with increasing the resin dosage from 5 g/L to 10 g/L. Copper removal was almost complete at the highest resin dosage tested (20 g/L). Similarly, high resin dosages (≥10 g/L) appeared to be required to achieve high adsorption recoveries (≥%97) for zinc and iron. These findings demonstrate that heavy metals (Cu, Zn and Fe) can be readily removed from cyanidation effluents by using Dowex 21K XLT anionic resin.

期刊介绍： Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
