INDICATOR FOR MERCURY CONTAMINATION AND AUXILIARY CLEANING AGENT

摘要

A powder mixture of either cuprous iodide or silver iodide with elemental sulfur is a mercury contamination indicator of high visibility and sensitivity. The buff or cream color of this mixture changes to black or dark brown in the presence of mercury or mercury vapor. The mixture may also be used in areas of light mercury contamination to decontaminate the area by reaction with the mercury.
