摘要
文章以活性炭和改性硅藻土作为吸附剂,对对硝基苯胺模拟废水进行了吸附实验。结果表明:吸附去除率受吸附剂投加量、废水初始浓度、吸附温度等因素影响,其中,实验范围内,温度为20℃,投加量为10 g/L,对硝基苯胺初始浓度为20 ppm条件下硅藻土对对硝基苯胺的吸附最有利,而温度为20℃,投放比0.33 g/L,对硝基苯胺初始浓度60 ppm条件下活性炭吸附对硝基苯胺最有利。
The treatment of p-nitroaniline wastewater by adsorption was studied. The diatomite and activated carbon were used as adsorbents. Under the reaction conditions in the work, the results indicated that the removal rate of p-nitroaniline was affected by temperature, initial p-nitroaniline concentration and dosage of adsorbents etc. For diatomite adsorbent, the optimized conditions were 20℃ of adsorption temperature, 10 g/L of dosage and 20 ppm of initial p-nitroaniline concentration. For activated carbon, the optimized conditions were 20 ℃ of adsorption temperature, 0.33 g/L of dosage and 60 ppm of initial p-nitroaniline concentration.
