Abstract
A process for removal and conversion into sulfur of hydrogen sulfide in a gaseous or liquid material which comprises essentially treating the said material with a nitrohumic acid or its salt prepared by treating humic acid with a nitrating agent and, if necessary, converting the resultant into an alkaline salt. The process is advantageous essentially in that hydrogen sulfide can be removed economically and converted into sulfur, and that the desulfurization agent, i.e. a nitrohumic acid or its salt is non-toxic and non-corrosive.
