Abstract: The choice of suitable conditions is first reported for the indirect spectropho-tometric determination of trace sulfide with the colour reaction of mercury ( Ⅱ)-Tetrakis(4-trimethylammoniumphenyl) porphyrin (TAPP). Common anions such as Cl-,Br-,I-,SO42-,NO3- and SCN- do not interfere in it, and CN- can be masked by formaldehyde. This method was used for the analysis of some industrial waste water and coal-gas with satisfactory results.
