摘要

采用微生物燃料电池(MFC)技术研究了纯四氯酸盐离子溶液中金的去除率。考察了阴极溶液类型和初始金浓度对去除率的影响。由于铜离子在金废水中的含量较高,研究了铜离子对金离子去除率的影响。考察了pH和初始生物量浓度对脱金效率的影响。结果表明,在常温条件下,酵母浓度为80 g/L,初始金离子浓度为250 ppm的废水中,接触时间为5 h后,金的去除率可达95%。在相同条件下运行48h后,98.86%的AuCl4 -离子被成功地从溶液中去除。废液中金的初始浓度为250 ppm, pH为2,酵母初始浓度为80 g/L,金的去除率达到100%。另一方面,在pH为5.2的条件下,废液中铜的去除率达到53%。

Removal of heavy metals from industrial wastewater using microbial fuel cell

Removal efficiency of gold from a solution of pure tetrachloroaurate ions was investigated using microbial fuel cell (MFC) technology. The effects of type of catholyte solution and initial gold concentration on the removal efficiency were considered. Due to its presence at high levels in the gold wastewater, the effect of copper ions on the removal efficiency of the gold ions was also studied. The effects of pH and initial biomass concentration on the gold removal efficiency was also determined. The results showed that after 5 h contact time, 95% of gold removal efficiency from a wastewater containing 250 ppm of initial gold ions at ambient temperature using 80 g/L yeast concentration was achieved. After 48 h of the cell's operation under the same condition, 98.86% of AuCl4 ions were successfully removed from the solution. At initial gold concentration in the waste solution of 250 ppm, pH 2, and initial yeast concentration of 80 g/L, 100% removal efficiency of the gold was achieved. On the other hand, the most suitable condition for copper removal was found at a pH of 5.2, where 53% removal efficiency from the waste solution was accomplished.

期刊介绍: Engineering in Life Sciences (ELS) focuses on engineering principles and innovations in life sciences and biotechnology. Life sciences and biotechnology covered in ELS encompass the use of biomolecules (e.g. proteins/enzymes), cells (microbial, plant and mammalian origins) and biomaterials for biosynthesis, biotransformation, cell-based treatment and bio-based solutions in industrial and pharmaceutical biotechnologies as well as in biomedicine. ELS especially aims to promote interdisciplinary collaborations among biologists, biotechnologists and engineers for quantitative understanding and holistic engineering (design-built-test) of biological parts and processes in the different application areas.
