Based on the phenomenon that NO2- can be permeated through the hydrophobic chlorinated polyvinyl chloride (CPVC) barrier fabricated in filter paper and the microfluidic paper-based devices (μ-PADs), the nitrite microfluidic detection chip by fabricating CPVC barrier in filter paper was carried out. The detection limit of the method is 48 μmol/L nitrite, and the linear range for nitrite is 70~1500 μmol/L. The method has been successfully applied to the determination of nitrite in Xi'an city moat water and sausage sample.

Key words: CPVC barrier, detection chip, nitrite, filter paper, measurement
