The PAN method is a highly sensitive and rapid procedure for detecting low
levels of manganese. An ascorbic acid reagent is used initially to reduce all
oxidized forms of manganese to Mn
mask any potential interferences. PAN Indicator is then added to combine with
2+
the Mn
to form an orange-colored complex. Test results are measured at
560 nm.
