摘要
对活性炭进行改性处理,考察了微波-硝酸改性活性炭、微波-硫酸亚铁改性活性炭对经氧化后的有机磷农药尾水中磷的吸附作用,以及微波功率、搅拌时间、硝酸浓度、硫酸亚铁浓度等影响因素对去除效果的影响。结果表明,经过硝酸和硫酸亚铁改性后的活性炭,对磷的吸附效果比未改性的活性炭更为显著。由于孔隙的扩张作用,经过微波加强后的改性活性炭对磷的吸附进一步提高。
The adsorption of phosphorus in the tail water of oxidized organophosphorus pesticide by microwave-nitric acid modified activated carbon and microwave-ferrous sulfate modified activated carbon was investigated,and the influence of microwave power,stirring time,nitric acid concentration,ferrous sulfate concentration and other factors on the removal efficiency was investigated also.The results showed that the adsorption of phosphorus by the activated carbon modified by nitric acid and ferrous sulfate was more significant than by the unmodified.Due to the expansion of pores,the adsorption of phosphorus on the modified activated carbon enhanced by microwave was further improved.
