NOVELTY - Removing at least one antibiotic from a dairy product comprises passing the dairy product comprising an antibiotic in a first amount through a bulk comprising, relative to a total bulk weight, at least 75 wt.% titanium oxide nanostructures, to provide the dairy product comprising the antibiotic in a second amount, where the first amount is greater than the second amount, and the nanostructures have lengths at least two-fold in excess of their width and height. USE - The method is useful for removing at least one antibiotic from a dairy product. ADVANTAGE - The method has loosely tangled, noodle-like morphologies on sub-100 nm scale, and need not employ graphene and/or polymeric support networks in columns, generally having only titanium oxides without silicon or iron oxides. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (a) a column, comprising a stationary phase comprising at least 90 wt.% titanium oxide nanotubes, relative to a total weight of the stationary phase and the nanotubes have an average diameter of 5-200 nm; and (b) a mixture comprising titanium oxide nanotubes having a formula HxNa2-xTi2O5.(H2O), where xless than or equal to2, an antibiotic and a dairy product.
