Hydrogen sulfide test kit and method for detecting hydrogen sulfide in an aqueous sample

Abstract

A hydrogen sulfide test kit includes a first reactant powder that includes citric acid, a second reactant powder that includes sodium bicarbonate, and a test paper that changes color upon contact with hydrogen sulfide. The first and second reactant powders are physically separated from each other. A method of using the hydrogen sulfide test kit and a method for detecting hydrogen sulfide in an aqueous sample bot include allowing the citric acid and the sodium bicarbonate to react in the aqueous sample to form air bubbles that release any hydrogen sulfide in the aqueous sample into gas form; contacting the released hydrogen sulfide in gas form, if present, with the test paper; and detecting the presence of hydrogen sulfide in the aqueous sample based on the color of the test paper.
