A procedure for the determination of hydrogen sulfide in fermentation broths containing up to 100 mug of SO(2) per ml is described. The method involves the sparging of H(2)S from the broth into a cadmium hydroxide absorption solution, the formation of methylene blue from the absorbed sulfide, and the measuring of this color spectrophotometrically. The use of cadmium hydroxide instead of zinc acetate, the common absorbent, substantially reduced the interference of SO(2) with the analysis.
