Sulfurated hydrogen commonly called hydrogen sulfide (H2 S) is a clear, colorless, extremely toxic gas that has a rotten egg smell at low concentration. The human nose can detect H2 S at concentrations below 100 parts per billion (ppb). It is found least amount in cigarette smoke that has been the subject of analysis for many analytical chemists. This gases is soluble in alkaline medium and gives free sulfide (S-2 ) ions. Sulfide ion concentration in cigarette smoke solution is found in the range of detection limit of lab made Silver- silver sulfide (Ag/Ag2 S) ion selective electrode (ISE).This project has designed to investigate the amount hydrogen sulfide as a free sulfide (S--)ion in cigarette smoke solution. Silver-silver sulfide ion selective electrode (Ag/ Ag2 S ISE) and Silver–silver chloride (Ag/AgCl) reference electrode are prepared in the lab for determination. Detail protocol of standard addition method with modified Grant’s plot is applied for estimation. Different brand of cigarette samples were collected from different area of Pokhara valley and analyzed. The average amount of H2 S per stick of cigarette smoke is found to vary from 0.0453 mg to 0.0573 mg in different brands. Among them sample no SA-5 shows 0.0453mg per stick of cigarette. This result is minimum in compare to other brands. Similarly, sample no SA- 7 have found 0.0573mg per stick which is higher in compare to other brands. Key words: Cigarette smoke, hydrogen sulfide, ion selective electrode, standard addition method, Grant’s plot method,
