| الوصف: | International audience ; This research intends to produce TiY2O5@g-C3N4 nanocomposite that can be utilized to eliminate Ba+2 from aqueous solutions. The nanocomposite was studied with XRD, BET, EDX, and TEM investigation. The TiY2O5@g-C3N4 nanocomposite sorption effectiveness was studied by contact time, adsorbent dose, beginning pH, and initial barium ions concentration in batch kinetic and equilibrium tests. The barium ions adsorption was conducted using 10 mg of adsorbent, 60 mg. L−1 initial Ba+2 concentration at pH = 7 and equilibrium was reached in within 54.5 min. The Langmuir isotherm offered the highest correlation for Ba+2 adsorption to TiY2O5@g-C3N4 and demonstrated favorable adsorption; a maximum adsorption capacity of 295.52 mg. g−1 was achieved. The experimental data was utilized to study adsorption mechanisms and potential rate-controlling stages for mass transfer and kinetic models. External mass transfer and intra-particle diffusion influenced barium adsorption, and adsorption's kinetics followed a pseudo-second-order model with R2 = 0.9996, t1/2 = 38.8 min and h0 = 1.51 mg.g−1.min−1. The results indicate that Ba+2 are chemisorbed on TiY2O5@g-C3N4 nanocomposite. The results indicate that the nanocomposite has high aptitude and reusability for an effective metal ions adsorption. |
