Equilibrium and kinetic studies of C.I. Basic Blue 41 adsorption onto N, F-codoped flower-like TiO2 microspheres

► A novel 3D N, F-codoped flower-like TiO2 structure was successfully synthesized. ► The as-prepared samples showed high absorption capacities for dye CB41. ► The adsorption of CB41 onto NFT-1 fitted well with Langmuir model. ► The pseudo-second order kinetic model described well for CB41absorption onto NFT-1. ► The adsorption process was feasibility, spontaneous and endothermic in nature.
