In this study, effective parameters on CO absorption using ethyl alcohol and iron solutions [time (15-75 min), temperature (36-40°C), concentration (0-40% v/v, of ethyl alcohol, 0-8%w/v, of iron solution), stirring rate (0-400 rpm)] and interactions of parameters with each other have been examined as the optimization method by using Design Expert method, 4 parameters and 5 levels. Mathematical optimization results are evaluated by finding the optimum points. As a result, the effects of parameters on CO absorption are comparatively investigated. It is observed that the parameters could interact binary and also influence CO absorption (R1). According to ANOVA analysis, the value of the quadratic model (p<0.0001) is found to be less than 0.05 and indicates that the model is meaningful for ethyl alcohol solution. The experimental data of the model is well represented for ethyl alcohol solution (R2=0.9426) and iron solution (R2=0.9384) as can be seen from correlation coefficients. The data are furnished via FT-IR spectra.

通过设计专家方法用铁和酒精溶液吸收一氧化碳

在这项研究中，使用乙醇和铁溶液吸收 CO 的有效参数 [时间 (15-75 分钟)、温度 (36-40°C)、乙醇浓度 (0-40% v/v、0-8铁溶液的%w/v)、搅拌速度(0-400 rpm)]以及参数之间的相互作用作为优化方法，采用Design Expert方法、4个参数和5个水平进行了研究。通过找到最佳点来评估数学优化结果。因此，比较研究了参数对 CO 吸收的影响。据观察，这些参数可以相互作用二元，也影响 CO 吸收 (R1)。根据 ANOVA 分析，二次模型的值 (p<0.0001) 小于 0.05，表明该模型对乙醇溶液有意义。从相关系数可以看出，模型的实验数据很好地代表了乙醇溶液（R2=0.9426）和铁溶液（R2=0.9384）。数据通过 FT-IR 光谱提供。
