Revised analysis of phosphorus adsorption mechanisms: response to Khim Hoong Chu's comment on our aerogel study....

We appreciate the constructive comments by Khim Hoong Chu regarding our recent study on phosphorus adsorption using red soil-based aerogel. In response, we have carefully re-examined the kinetic and isotherm modeling approaches, providing additional clarifications and corrections where necessary. Revised analyses confirm that the core findings of our study remain valid, though some model formulations have been refined to improve accuracy. Further experimental validation supports the effectiveness of the aerogel in phosphorus immobilization. This reply addresses the raised concerns while reinforcing the robustness of our original conclusions.
