ABSTRACT:
A molybdenum salt-palladium salt solution for CO detection is made reversible by addition of ferric ion. The system is made more CO specific by adding an interference control salt which forms white or colorless precipitates with interfering species. The operational and shelf life are extended by a mixture of counterions; the acetate counterion is particularly useful.
