| titleOfInvention | The step colour developing examination method of forbidding azo dyes in dyed textiles |
| abstract | The invention discloses a kind of step colour developing examination method of forbidding azo dyes in dyed textiles, comprise the following steps：（1）Sample is reduced；（2）Colour developing：In the same position of filter paper, first it is added dropwise one and drips developer, then 12 drop t-butyl methyl ether extract solution colour developings are added dropwise；The developer is the paradime thylaminobenzaldehyde of mass volume ratio 0.1%~10% and the ethanol solution of the hydrochloric acid of volume ratio 10%~25%；（3）Screening judges：Whether occurs obvious color change after dropwise addition sample solution come judged result according on developer：If obvious color change does not occur after sample solution colour developing, represent that thing to be checked or its concentration are not contained in sample is less than test limit, be as a result feminine gender；If occurring obvious color change after sample solution colour developing, then it represents that forbidding azo dyes may be contained in sample, be as a result the positive, need to be further confirmed that by chromatographic apparatus.Of the invention simple, quick, direct chromogenic assay after sample reduction, whole process color can be completed in 1min. |
