This review covers research on the use of potassium hydroxide (KOH) to produce and modify activated carbon. The methods employed for activation by considering the activation process, carbonization, temperature, activation time, and KOH ratio to material are described and how the surface area, surface morphology, and functional groups are affected by the KOH ratio. Characterization techniques and preparation conditions are summarized. The activated carbon pore structure mainly depends on the burn-off size and the time for activation is linked to the overall activation reaction rate. The increase in surface area and pore size depends on the ratio of KOH, showing that KOH affects the surface chemistry of the activated carbon. The sorbent-sorbate interactions are strongly influenced by different parameters, which were also calculated in this review and used to evaluate such interactions.

KOH活性炭的改性、生产和方法

本综述涵盖了使用氢氧化钾 (KOH) 生产和改性活性炭的研究。通过考虑活化过程、碳化、温度、活化时间和 KOH 与材料的比例来描述用于活化的方法，以及 KOH 比例如何影响表面积、表面形态和官能团。总结了表征技术和制备条件。活性炭孔结构主要取决于烧尽尺寸，活化时间与整体活化反应速率有关。表面积和孔径的增加取决于 KOH 的比例，表明 KOH 会影响活性炭的表面化学性质。吸附剂-山梨酸盐的相互作用受不同参数的强烈影响，
