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
Objective: The present study aimed to investigated the surface-modified TiO2 by MoS2
Method: The effects of surface enhancement on as-prepared adsorbents on adsorption of
methylene blue (MB) was 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.
