Study of the effect of temperature, pH, and time on the desorption of H2S.

Abstract

Water is an inexhaustible natural resource, however, for use in human activities, it is required that its present certain characteristics that make it seem scarce. Hydrogen sulphide is a contaminant that occurs in well water making the water unusable for any human activity. Technology-marginalized areas that have this type of problem are affected by not having tools or equipment that can remove hydrogen sulphide from water. This study focuses on presenting an experimental design to determine the H2S removal kinetics under standard pressure conditions at different temperatures (23°C, 40°C and 50°C), observing that at 50°C up to 40% of the water evaporated. In addition, the effect of temperature (23°C and 40°C) and pH (7 and 11) on the removal of hydrogen sulphide was observed. An ANOVA was performed with the results obtained, determining that the significant variable in these tests was pH.
