In this work, the direct determination of H{sub 2}S in sewage samples was determined using a method which involves bubbling nitrogen through the aqueous sulfide solution to strip all the H{sub 2}S which could escape to the gas phase and measure it by and H{sub 2}S-gas detector. The amount of molecular H{sub 2}S was determined from the calculation of the total area under the curve relating the volume of nitrogen (L) and H{sub 2}S concentration (mg/L) in the gas phase. The area was calculated using the Trapezoidal Numerical Method. The H{sub 2}S for the same sewage sample was also determined by using the standard iodine method.
