Valorization and Evaluation of Terminalia Ivorensis Fibrous Waste for Its Environmental Sequestration Potential for Industrial Anionic Dyes in Aqua System
This research depicts the pragmatic sequestration capacity of ubiquitous Terminalia ivorensis tree bark (TITB) on toxic anionic dyes (congo red (CR), methyl orange (MO), chlorophenol red (CPR), and Eosin Y (EY)) from aqua system.

| description | This research depicts the pragmatic sequestration capacity of ubiquitous Terminalia ivorensis tree bark (TITB) on toxic anionic dyes (congo red (CR), methyl orange (MO), chlorophenol red (CPR), and Eosin Y (EY)) from aqua system. Surface characterization of TITB by bulk density, Boehm titration, pH of point of zero charge (pHPZC), field emission-scanning electron microscopy (FE-SEM) and Fourier transform infrared (FTIR) spectroscopy revealed that TITB comprise rough intertwined texture with some functional moieties which adsorbed the industrial dyes. The adsorption capacities ($${q_e}$$) of MO, CR, and EY were maximum at pH 2.0 ($${q_e}$$= 84.59, 92.67 and 92 mg.g−1 respectively) while that of CPR was maximum at pH 6.0 ($${q_e}$$= 99.05 mg.g−1). Langmuir monolayer coverage capacity ($${q_{\max }}$$) of TITB was obtained for the adsorption of EY, which was 142.45 mg.g−1. Adsorption kinetics conformed to pseudo-second order kinetic model with a rate constant, $${k_2}$$ ≤ 0.9702 min−1. The change in Gibbs free energy (ΔG°) for the adsorption process was found to be negative showing that the maximum adsorption was spontaneous at operational temperatures for all dyes. Enthalpy and entropy change (∆H° and ∆S°) were positive for CR, MB, and EY describing endothermic form and increased disorderliness between the adsorbent-dye interface. |
