| Abstract: | Based on the phenomenon that NO-2 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. |
