摘    要:建立了香蕉皮快速、高效对重金属离子铅吸附性能的方法。采用分光光度法测定重金属离子铅的浓度,分别研究了7种不同形态的吸附剂对废水中重金属离子铅的吸附性能。在优化的实验条件下,重金属离子铅浓度与吸光度的线性相关系数R=0.999 83,且方法相对标准偏差(RSD)低于3%。结果表明,香蕉皮对废水中的重金属离子铅有良好的吸附效果,吸附率达到91.3%。利用香蕉皮去除废水中的重金属离子,可以变废为宝,且方法吸附率高、准确可靠、精密度高,可用于吸附废水中重金属离子铅。

关 键 词:香蕉皮  铅离子  吸附  分光光度法

Abstract:A fast and efficient method for the adsorption of heavy metal ions lead with banana peel was developed. The concentration of heavy metal ions lead was measured by spectrophotometry. The effects of seven different types of adsorbents on heavy metal ions in wastewater were studied. Under the optimized experimental conditions, the linear correlation coefficient of heavy metal ions lead concentration and absorbance was R=0.99983. The relative standard deviation (RSD) was below 3%. The results showed that banana peel has good adsorption effect on heavy metal ions lead in wastewater. And the adsorption rate is 91.3%. Using banana peel to remove heavy metal ions from wastewater can be turned into treasure. The method has high adsorption rate, accurate reliability and high precision. It can be used to adsorb heavy metal ions lead in wastewater.
Keywords:banana peer   Pb2    adsorption   spectrophotometric
