Pillared sodium bentonite (BSP) and pillared calcium bentonite (BCP) were prepared by means of the sol–gel method using titanium tetraisopropoxide with calcination for 3 h at 500 °C. They were characterized using the BET method for N2 adsorption, and subjected to X-ray diffraction and Fourier transform infrared spectroscopy. The results show that the surface area of the pillared bentonites increased after the process, more than the natural ones. Pillared sodium bentonite has a more porous structure, larger surface areas, and higher adsorption capacity than pillared calcium bentonite. The kinetic adsorption of ciprofloxacin (CIP) onto pillared bentonites is well described by the pseudo second-order kinetic model. The BSP isotherm well fitted the Freundlich model, while the BCP isotherm fits the BET model better, suggesting multilayer adsorption. DR model shows mostly physical adsorption for CIP on the two adsorbents. The pH influence study indicated that CIP is adsorbed at pH between 6 and 8, which facilitates the use of BCP and BSP in wastewater treatment, whose pH generally oscillates between these ranges. 000126530 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000126530 590__ $$a3.0$$b2023 000126530 592__ $$a0.724$$b2023 000126530 591__ $$aWATER RESOURCES$$b40 / 128 = 0.312$$c2023$$dQ2$$eT1 000126530 593__ $$aAquatic Science$$c2023$$dQ1 000126530 591__ $$aENVIRONMENTAL SCIENCES$$b169 / 358 = 0.472$$c2023$$dQ2$$eT2 000126530 593__ $$aWater Science and Technology$$c2023$$dQ1 000126530 593__ $$aGeography, Planning and Development$$c2023$$dQ1 000126530 593__ $$aBiochemistry$$c2023$$dQ2 000126530 594__ $$a5.8$$b2023 000126530 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126530 700__ $$aPeñafiel, María Eulalia 000126530 700__ $$aMontero, Carolina 000126530 700__ $$0(orcid)0000-0002-2494-102X$$aMenendez, Miguel$$uUniversidad de Zaragoza 000126530 700__ $$aPinos-Vélez, Veronica 000126530 7102_ $$15005$$2555$$aUniversidad de Zaragoza$$bDpto.
