摘要
采用铁锰表面改性活性炭,进行对水中的2,4,6三氯酚的动态吸附实验研究,实验表明铁锰改性活性炭动态吸附2,4,6三氯酚受到水样初始浓度、初始pH值和流速等因素的影响。另外,采用质量分数为4%的NaOH在10℃的振荡器内振荡24h,再生铁锰改性活性炭,发现经过3次再生后,仍能保持较好的吸附性能。
Surface of granular activated carbon modified by Fe and Mn is used in the experimental study of dynamic adsorption of 2,4,6-trichlorophenol(TCP) in water.It is showed that the adsorption effect of 2,4,6-trichlorophenol with granular activated carbon modified by Fe and Mn is affected by initial water concentration,initial pH value and flow rate,etc.In addition,to recycle granular activated carbon modified by Fe and Mn,it is oscillated with NaOH solution(mass fraction is 4%) in oscillator at 10 ℃ for 24 h.It is found that the adsorption capability is still good after three times of regeneration.
