WebbThere are two key methods used to obtain oxygen gas. The first is by the distillation of liquid air. The second is to pass clean, dry air through a zeolite that absorbs nitrogen and leaves oxygen. A newer method, which gives oxygen of a higher purity, is to pass air over a partially permeable ceramic membrane. WebbApart from diffusion from the air, water bodies gain oxygen through photosynthesis of chorophyll bearing aquatic organisms i.e. higher plants, phytoplankton and photosynthetic bacteria. Oxygen is lost from the water body by the respiration of animals and plants and also by decomposition of organic matter.
