Abstract
The present invention relates to a method for removing sulfur from a gaseous or liquid mixture. This method involves contacting the gaseous or liquid mixture with an iron-enriched matrix under conditions effective to remove sulfur from the mixture through adsorption of the sulfur to the matrix. The iron-enriched matrix used in this method is a lignocellulosic material that is enriched with iron. The present invention also relates to a system, composition, and plant fertilizer that contain the iron-enriched matrix. Methods of making the composition and preparing a plant fertilizer are also disclosed.
