摘要
The incorporation of sulfide into methylene blue in the presence of acidic N,N-dimethyl-p-phenylenediamine and ferric chloride has been utilized to provide a direct determination for sulfide at concentrations of 2 to 80 mμmoles per milliliter. No distillation step is required. At concentrations of 10−3M, only slight interference by organic thiols was observed. Advantages in sensitivity, specificity, color stability, and convenience are offered over earlier methods.
