Analisis Efektivitas Penyisihan Hidrogen Sulfida (H2s) dengan Metode Adsorpsi Menggunakan Zeolit pada Air Sungai Aek Singolot

Abstract

Hydrogen Sulfide is one of the parameters that exist in the characteristics of river water. Hydrogen sulfide is a poisonous gas, is corrosive and can dissolve in water. One of the treatments that can be used to remove hydrogen sulfide concentrations is by adsorption. This research was conducted to see the effect of variations in the mass of the adsorbent (0.1, 0.2, 0.3 and 0.4) grams and variations in contact time (15, 30, 45 and 60) minutes on the efficiency of hydrogen sulfide removal parameters in water. river. After being analyzed, it was found that with a mass of 0.4 gram adsorbent at a contact time of 60 minutes, the greatest efficiency was obtained at 95.87%. Based on the results of the ANOVA test, it was obtained that 90.1% of the variables used simultaneously affected the decrease in hydrogen sulfide concentration. The data resulting from the adsorption process were then analyzed to find out the appropriate kinetics model and adsorption isotherm. It has been obtained from the analysis results that this adsorption process follows the second order pseudo adsorption kinetics model and the Freundlich adsorption isotherm model
