摘　　要：Industry progressing caused the pollutants into the surface and groundwater,including organic pollutants such as phenylenediamine(PD)and heavy metals such as Cr(Ⅵ).Herein,a simple"three-in-one"strategy based on MOF-199 was demonstrated.The MOF-199 catalytic system could be used for the rapid detection of Cr(Ⅵ)and o-phenylenediamine(OPD)in linear ranges of 0.5-50.0μmol/L and 7.0-250.0μmol/L,with the limits of detection of 0.1 and 0.5μmol/L,respectively.This method can also efficiently discriminate PD isomers in just 15 min.Meanwhile,Cr(Ⅵ)was reduced to Cr(Ⅲ)and the elimination of OPD was carried out.Given simple synthesis,high sensitivity,easy operation,and low cost,this method presented a potential platform for on-site detection of pollutants in water samples.
