Optimum physical and chemical conditions for the Methylene Blue method of estimating gaseous sulphide in the environment.
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.
