【摘要】：水体中壬基酚的存在危害着人类的健康,因此研究出一种经济、有效的壬基酚去除方法迫在眉睫。通过对多种吸附剂的比较,选定松针作为吸附剂,以此来去除水体中的壬基酚。以静态实验,考察温度,时间,pH值,吸附剂用量等条件对吸附行为的影响,同时进行相应的吸附动力学分析和吸附热力学分析。研究表明,当浓度为10mf/L,温度25℃,pH为7,吸附剂投加量为10g时,去除率达到96%以上。吸附过程符合Freundlich吸附等温线,一次动力学吸附模型。以动态实验,考察进水流速,浓度等条件对吸附过程的影响,确定穿透时间和穿透点,建立相应的动态吸附模型,为工业应用奠定理论基础。
[Abstract]:The existence of nonylphenol in water is harmful to human health, so it is urgent to develop an economic and effective nonylphenol removal method. By comparing various adsorbents, pine needles were selected as adsorbent to remove nonylphenol from water. The influence of temperature, time, pH value and the amount of adsorbent on the adsorption behavior was investigated by static experiment. The adsorption kinetics and thermodynamics were also analyzed. The results show that the removal rate is over 96% when the concentration is 10 MF / L, the temperature is 25 鈩，
