The invention discloses a sulfonic acid zinc metal organic complex, which relates to the technical field of organic synthesis, the complex is 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex, the chemical formula of the 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex is Zn (8-aql)2(1,5-nd).2H2O, the invention also provides a preparation method of the complex, which comprises the following steps: reacting zinc nitrate hexahydrate, sodium azide, 1, 5-naphthalene disulfonic acid sodium salt and 8-aminoquinoline in secondary deionized water at 120-180 DEG Cfor 3 days, cooling to room temperature, filtering, and washing to obtain the complex. The invention also provides the application of the complex in detection of carbon disulfide and nitrobenzene. The 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex has the beneficial effects that the 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex prepared by the method can be used for detecting low-concentration carbon disulfide in the environment and can also be used for detecting low-concentration nitrobenzene in the environment.
