采用加入0.5%4-F苄基取代吲哚嗪衍生物作为缓蚀剂在90℃、20 wt.%盐酸中的失重评价数据来研究其在盐酸中的吸附行为。吸附热力学是通过研究缓蚀剂的浓度C与浓度和覆盖度比值（C/θ）之间的关系曲线，并对得到的关系曲线进行拟合，确认最符合的等温吸附模型来计算相关的吸附热力学参数。

Weight loss evaluation data using the addition of 0.5% 4-F benzyl-substituted indolizine derivatives as corrosion inhibitors at 90°C in 20 wt.% hydrochloric acid.Adsorption thermodynamics is to calculate the relevant adsorption thermodynamic parameters by studying the relationship curve between the concentration C of the inhibitor and the ratio of concentration and coverage (C/θ), and fitting the obtained relationship curve to confirm the most consistent isothermal adsorption model.
