摘要
还原铁粉用稀酸淋洗后用于还原对硝基苯酚(4-NP)。考察了酸种类、酸浓度和铁粉用量对反应的影响,结果表明,用硫酸、盐酸和硝酸处理铁粉后,其还原效果均得到提高,其中用盐酸处理的铁粉效果最好。用不同浓度的盐酸处理铁粉,其中用0.1mol·L^(-1)盐酸处理的效果最好。
Iron washed with acid was used to degrade 4-nitrophenol (4-NP).The effects of acid kind, acid concentration and iron dosage were investigated.The results showed that degradation of 4-NP could be promoted by washing iron with acid. Among the 3 kinds of acids, sulfuric acid,hydrochloric acid andnitric acid,hydrochloric acid had the best effect.The suitable concentration of hydrochloric acid was 0.1 mol/L.
