title: Optimum physical and chemical conditions for the Methylene Blue method of estimating gaseous sulphide in the environment.
abstract: The sensitivity and reproducibility of the Methylene Blue method for gaseous sulphide estimation have been investigated with respect to physical conditions and the concentrations of the reagents, especially sulphuric add. A new design of absorber is proposed to minimize gas-phase loss of the sulphide in the final stage of the procedure.
