Citric acid-modified loquat seed waste as biosorbent for methylene blue: kinetics, isotherm, thermodynamics, and machine learning-based prediction of adsorption performance
Graphical abstract showing citric-acid modification of loquat seed powder and its application as a biosorbent for methylene blue removal. The material achieved a maximum adsorption capacity of 47.53 mg/g within 9 min, followed by the Freundlich and pseudo-second-order models, which were accurately predicted by a rand...
