The organic impurity and its occurrence in industrial waste salt affect the salt resource utilization. In this paper, composition quantitative analysis, XRD, TG-DSC, SEM\/FIB-SEM coupled with EDS, FTIR, XPS and GC-Ms were chosen to investigate the organic impurity and its occurrence in industrial waste salt. The organic impurities owe small proportion (1.77%) in the specimen and exhibit weak thermal stability within the temperature of 600\u00b0C. A clear definition of organic impurity, including 11 kinds of organic compounds, including aldehyde, benzene and its derivatives etc., were detected in the industrial waste salt. These organic impurities, owing (C-O\/C-O-C, C-OH\/C = O, C\u2013C\/CH<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub>\/C = C etc.)-containing function group substance, are mainly distributed both on the surface and inside of the salt particles. Meanwhile, the organic substance may combine with metal cations (Ni<jats:sup>2+<\/jats:sup>, Mg<jats:sup>2+<\/jats:sup>, Cu<jats:sup>2+<\/jats:sup> etc.) through functional groups, such as hydroxide, carbonyl etc., which increases its stability in the industrial waste salt.
