Although experimental design is important in many fields and industries, most undergraduate students do not get exposure to this in a standard lab curriculum. This work describes a student-designed, multiple-week, flexible chemistry experiment with environmental applications that include factorial experimental design and analysis of variance statistical analysis. Through the experiment, students attempt to gain a better understanding of activated carbon adsorption of dyes under a set of factors, which could include type of dye, type of carbon, pH, salinity, hardness, and time of contact, each at multiple levels. The experiment is easily adaptable for a range of student enrollments and uses only common laboratory glassware and any visible spectrometer.

灵活的实验介绍析因实验设计

尽管实验设计在许多领域和行业中都很重要，但是大多数本科生并没有在标准实验室课程中接触到这一点。这项工作描述了一个学生设计的，为期数周的灵活化学实验，并具有环境应用程序，其中包括析因实验设计和方差统计分析。通过该实验，学生试图在一系列因素下更好地理解染料对活性炭的吸附，这些因素可能包括多个级别的染料类型，碳类型，pH，盐度，硬度和接触时间。该实验很容易适应一系列学生，并且仅使用普通的实验室玻璃器皿和任何可见光谱仪。
