Xenon
Xenon is a colourless, odourless noble gas and is very unreactive. It is present in small amounts in air and is used in lamps, flash tubes, some medical applications and ion-propulsion systems. At room temperature it is a gas; the density shown is for gaseous xenon near 20 °C.
Xenon is not ordinarily considered a dissolved-metal contaminant in process water. Its relevance to water systems would generally depend on a specific gas-handling, research or nuclear-related application.
Xenon in water treatment
Water-treatment context: Conventional dissolved-metal treatment is not applicable to xenon gas. If xenon is relevant to a particular process, assess the gas source, gas–liquid contact and system purpose rather than treating it as an aqueous metal ion.
Elemental substances and dissolved or gaseous species behave differently in water. Water chemistry and the exact chemical form must be considered when assessing treatment.
