研制了硫化物微生物传感器并用于测定硫化物。该传感器对 S2 -的测定线性范围为 0 .0 3～ 3.0 0 mg/L,测定一个样品需 2～ 3min;实验选出了最佳测试条件和用于实际样品分析 Sulfide microbiological sensors were developed and used to determine sulfides. The linearity of S2 - was 0.03 ~ 3.0 0 mg / L, and the determination of one sample took 2 ~ 3 min. The optimal test conditions were selected and used for actual sample analysis
