We present a fast method to chili rasbora for sale monitor hydrogen sulfide (H2S) in ambient air based on a visible color change.Therefore, an immobilized copper(II) complex of the azo dye 1-(2-pyridylazo)-2-naphtol (H-PAN) was synthesized and prepared in a matrix for screen printing.Different materials, reaching from opaque paper to transparent foils served as substrate.The reaction of the copper(II) complex (Cu-PAN) to the target gas H2S c5 corvette radiator support was measured in reflection via UV/VIS spectroscopy.
