摘要
采用硝酸浸泡氧化方法改性碳纳米管,用于吸附水溶液中Fe3+的实验研究,用分光光度法进行测定。结果表明,改性碳纳米管吸附去除Fe3+效能较未改性的碳纳米管有显著的提高。通过对吸附数据的拟和,发现在所研究的温度范围内吸附等温线符合弗仑德利希(Freundlich)吸附等温式。
The nitric and acid was used to oxidative modify carbon nanotube , and the adsorption of Fe^3+ by modified carbon nanotube was investigated. The results showed that the adsorption ability and efficiency for Fe^3+ are much higher than before. The adsorption isotherm is in accord with Freundlich equation in the research temperature scope.
