Removal of Congo Red, Patton Reeder's, and Rhodamine B Dyes from Aqueous Solution Using Tabebuiarosea Peel as Natural Adsorbent

In this present study, batch experiments were conducted for the removal of Congo red, Patton Reeder's, and Rhodamine B dyes from water utilizing Tabebuia rosea as an adsorbent. The imperative need for employing an economical and environmentally friendly adsorbent to eliminate Congo red, Patton Reeder, and Rhodamine B dyes from aqueous solutions cannot be overstated. We carried out batch operations in the liquid phase to assess the influence of several experimental parameters, including pH, contact time, initial concentration of Congo red, Patton Reeder, and Rhodamine B, adsorbent dosage. Subsequently, validated the optimal conditions for these parameters to effective removal dyes. We also conducted a thorough examination of various characteristics of the Tabebuia rosea peel sample. Furthermore, in the present study focuses on adsorption isotherms and recommended the most suitable models for these isotherms. The equilibrium data were fitted with the Langmuir and Freundlich adsorption isotherms, with the results indicating that the Freundlich isotherm provided a better fit than the Langmuir isotherm. The findings suggest that Tabebuiarosea peel can serve as a cost-effective and efficient alternative for treating effluents containing Congo red, Patton Reeder, and Rhodamine B dyes.
