Water pollution has increased in recent years with pharmaceutical pollutants, such as tetracycline pollution. This pollutant has a harmful effect on the environment, water resources, agriculture, and drinking water for humans, animals, and agriculture. This research aims to use some nano oxides (vanadium pentoxide and nickel oxide) as an adsorbent material to remove this pollutant from water. The thermal method (reflex) was used to prepare vanadium pentoxide and the Sol–Gel method was used to prepare nickel oxide. The prepared oxides were calcined at 500 °C and then characterized by several methods, including UV/Visible, FTIR, XRD, SEM, and AFM. These prepared oxides were used to remove tetracycline from aqueous solution, and these prepared nano oxides showed variation in their removal efficiency (%R and qt), depending on the type of nano and its calcination temperature. Vanadium pentoxide ranked first in removal in both cases (as prepared and calcination), and the first case (as prepared) was considered the best, so it was adopted for optimal working conditions in terms of the best weight of the adsorbent material (nano), the highest concentration of the pollutant (tetracycline), the highest concentration of the detector (permanganate), the fastest stirring speed, and the best stirring time. Isotherm calculations were also performed using Langmuir and Freundlich equations.
