Abstract
Due to the increasing need for Oxygen-18 isotope in medical centers to produce 18F radioisotopes used in positron emission tomography (PET) centers, research is today more necessary than ever to improve and increase the production efficiency of this isotope. The concentration of oxygen-18 in water is 5.4% in this study, in a pilot distillation tower and in a total reflux state, two packings of coated Dixon and coated Sulz
