Adsorption of methylene blue and malachite green was carried out using Luffa cylindrica sponges as adsorbing material. We provide a very illustrative exercise about the use of common natural materials requiring little preparation to solve environmental tasks in a routine laboratory situation such as using dyes. In addition, the experiment can be used in different study levels. We illustrate the use of spectrophotometric techniques, calibrations, or (in a more advanced level) calculations of adsorption kinetics and the use of statistical tools in data treatment. The use of natural fibers to remove dyes from laboratory wastewater highlights the environmental responsibility of undergraduate students by training them to treat common laboratory pollutants, and on the other hand, it offers an efficient tool to illustrate water remediation procedures.

丝瓜天然纤维对普通实验室染料的吸附

使用Luffa cylindrica进行亚甲基蓝和孔雀石绿的吸附海绵作为吸附材料。我们提供了一个非常说明性的练习，说明了在日常实验室情况下（例如使用染料）使用很少的准备即可解决环境任务的普通天然材料的使用。此外，该实验可用于不同的研究水平。我们举例说明了使用分光光度法技术，校准或（更高级的）吸附动力学计算方法以及在数据处理中使用统计工具的方法。使用天然纤维去除实验室废水中的染料突出了大学生对环境的责任，方法是对他们进行培训以处理常见的实验室污染物，另一方面，它为说明水修复程序提供了有效的工具。
