Abstract
The tin(II)-diphenylcarbazide complex, [Sn(C13H14N4O)2]Cl2 or [Sn(C13H14N4O)2Cl2], applied as an acetone solution to cellulose (filter paper) or starch and dried, is oxidized to the red-violet diphenylcarbazone by ozone and nitrogen dioxide - the principal atmospheric oxidants - at concentrations below 1 ppm. The supported reagent is stable indefinitely when kept in a sealed bottle.Keywords
