The invention discloses a medicament for stabilizing sulfide contaminated soil, the medicament comprises a calcium-containing compound component and an iron-containing compound component, and the medicament has low cost, short time for treating of the sulfide-contaminated soil and no secondary pollution to the soil, can effectively stabilize sulfides in the soil, reduce the hydrogen release content of the sulfides in the soil when meeting an acid, and reduces the total acid leaching amount of the sulfides in the soil from 3000mg/kg to 57mg/kg (detected by p-aminodimethyl aniline spectrophotometric method). 本发明公开了种用于硫化物污染土壤稳定化的药剂，其包括含钙化合物和含铁化合物组分，该药剂成本低，处理硫化物污染土壤过程耗时短、对土壤无二次污染，且可以有效稳定土壤中的硫化物，降低土壤中硫化物遇酸释放硫化氢的含量，可将土壤中硫化物酸浸总量从3000mg/kg以上降低至57mg/kg(对氨基二甲基苯胺光度法检测结果)。
