Toxic pollutant online analyzer

This product uses the isonicotinic acid-barbituric acid spectrophotometry to determine the concentration of cyanide in water samples. After the water sample and the regulator are mixed, the cyanide ions in the water sample react with chloramine T to generate cyanogen chloride, which reacts with isonicotinic acid to generate glutaraldehyde after hydrolysis, and then reacts with barbituric acid to generate a purple-blue compound. The monitor detects the change in color and converts this change into a vapor value for output.

This product uses fluorine reagent spectrophotometry to determine the fluoride concentration in water. Fluoride ions, in an acetate buffer medium at pH 4.1, react with fluorine reagent and lanthanum nitrate to form a blue ternary complex. The color intensity is proportional to the fluoride ion concentration. Fluoride (F-) is quantitatively determined at a wavelength of 620nm.

This product uses 4-aminoantipyrine spectrophotometry to determine the concentration of volatile phenols in water. Photoelectric colorimetry is used for determination. After the water sample and the regulator are mixed, the volatile phenols in the water sample react with the indicator in the presence of a sensitizer to generate a colored complex. The monitor detects the change in color and converts this change into a volatile phenol value for output.
