Box 5085 Dakar-Fann, Senegal > Research Paper 2017 8 1 2017 11 18 The elimination of fluoroquinolone antibiotic, ofloxacine, was carried out by adsorption on titaniferous sand with a 58% content of TiO2. Various parameters such as contact time, sand concentration and initial pH influencing the adsorption of the antibiotic were optimized. Thus, the adsorption equilibrium was obtained after 100 minutes and the kinetics followed the second pseudo order model. The removal of the ofloxacine was better at a pH of 6.5 for a sand concentration of 160 g / L. Among the isothermal models tested, to represent the experimental results, the Langmuir model better described the adsorption process with a maximum adsorption capacity of 1.1383 mg/g and a kinetic constant of 0.0389 L / mg.
