Standardized Detection Method for Formaldehyde in Furniture Based on Fluorescent Probes
WANG Xing-di （DezhouProductQuality StandardMetrologyResearch Institute）
Abstract：Thispaper establishesastandardized method forrapidandaccurate formaldehydedetectionin furniture using fluorescent probes.By optimizing probe structure and detection conditions，a complete process for sample collection，preprocessing，and detection is developed.The method shows a strong linear relationship （ R2=0.9986 inthe range of 0.01～10.0mg/L ，with a detection limit of 0.005mg/L and the intra-day and inter-day precision （RSD） below 3% .Ithas excellntanti-interference ability，withthesignal changeofmain interfering substancesataconcentration of 50 times being less than ±5% .In actual sample testing，the relative deviation is under 5% ，compared with the HPLC referencemethod.This method is simple tooperate，andrespondsquickly，which is suitable forqualitycontroland standardizeddetectionofformaldehydein furniture.
