To evaluate the effect of potassium hydroxide activation on the adsorption efficiency of Chlorella-derived biochar for methylene blue.
Preparation of activated carbon from Chlorella through carbonization and KOH activation.
Evaluation of adsorption capacity before and after activation using methylene blue.
Analysis of adsorption isotherms using Langmuir, Freundlich, and Temkin models.
Raw Chlorella had an adsorption capacity of 287.2 mg g −1, reduced to 214.8 mg g −1 after carbonization.
KOH activation increased the adsorption capacity to 329.7 mg g −1, a 15% improvement over raw material.
The Freundlich model best fit the adsorption data with R 2 = 0.93, indicating multilayer physisorption.
