| 摘 要： | 用对二甲氨基苯胺作显色剂，在665nm处，用流动注射分光光度法研究了硫化物的稳定性。试验表明：用除氧水（pH＝11）配制硫离子浓度为50mg／1的硫化物标准贮备液，并将其盛于棕色瓶内，保存于冰箱（3℃）中，该液可稳定放置400小时。

| Abstract: | Stable characters of sulfide in the flow injection spectrophotomery method are studied. Reagent is a N. N-dimethy laniline. Working wave is at 665nm. The Standard prepared solution of sulfied is made up of oxyen-denuded (pH=11). The con centration of sulfidion is 50mg/1 in solution. The solution will be stable for 400 hours when it is kept in brown glass and ice box (3℃). |
