Abstract:


Background: Dyes are used in various sectors, such as the industry, textile, leather, and plastic industries, and part of these dyes is released in the environment via wastewater.

Objective: The present study aimed to investigated the surface-modified TiO2 by MoS2 and Cu.

Method: The effects of surface enhancement on as-prepared adsorbents on adsorption of Methylene Blue (MB) was were studied in a batch system by considering various parameters such as contact time, initial dye concentration and temperature.

Result: The results show that the adsorption process was well fitted with the pseudo-firstorder kinetic model (R2 = 0.99). Further, the equilibrium data for the adsorption process have beenwere evaluated using Langmuir, Freundlich, and Temkin isotherms.

Conclusion: The adsorption isotherm of MB onto as-prepared adsorbents nanoparticles fitted into the Freundlich equation.

Keywords:

Synthesis of pure doped and co-doped TiO2, surface analysis, adsorption, methylene blue dye remove from aqueous solutions, dyes, nauoparticles.
