摘要
本研究利用泡沫萃取法处理含铊工业废水,分离泡沫相和水相,通过火焰原子吸收分光光度法测定水相中铊浓度。采用泡沫萃取法能够有效的去除含铊重金属废水,尤其对基质较复杂,盐基度高废水有良好的去除效果。实验结果表明:当废水与萃取剂体积比125:1和50:1,铊去除率达80%和95%。该方法污染小、效果稳定、操作简便。
This study used Flota-extraction to treat Tl-bearing industrial wastewater, separation aqueous phase and foam layer, through flame atomic absorption spectrophotometric method to detect thallium concentration in aqueous phase. Using Foam-Extraction method can effectively remove heavy metal waste water containing thallium, especially for waste water with complex contaminant and a high salinity has good removal effect. By experimental verification, the ratio of wastewater to extractant is 125:1 and 50:1, the removal rate of Tl could reach 80% and 95%. This method has got the characteristics of lower pollution, steady effect and user-friendly control.
