Adsorption Kinetics and Isotherm Study of Basic Red 5 on Synthesized Silica Monolith Particles

The Silica monolith particles (SMP) were prepared from Tetra-Methyl-Ortho-Silicate (TMOS) and characterized by Fourier transforms infrared (FTIR), Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), surface area analyzer. FTIR analysis showed the Si?O stretching confirming SMP formation. SEM provided information about mean diameter of (1?5 µm). EDX confirmed presence silicon oxygen in SMP. Moreover, calculated for was found to be around 367 m2/g, whereas BJH pore size distributed 87.15 along with total volume radius 0.073 cm3/g 16.627 Å, respectively. Besides, removal efficiency 96%. Various kinetic equations used calculate adsorption parameters. Overall, results show that most appropriate model kinetics data pseudo-second order while mechanism best explained Langmuir isotherm. highest Basic Red 5 dye after 120 min at 298 K 576 mg/g. thermodynamics parameters (Enthalpy, Gibb’s energy, Entropy) also estimated. ?H° (0.995 kJ/mol) value depicted endothermic nature process. non-spontaneous aspect process evident ?G° values which 60.431, 328.93, 339.5 kJ/mol 293, 303, 313 K, From high value, it can concluded adsorbent a potential reclamation dyes wastewater.
