Nanomaterial adsorbent from waste from the system of flue gas desulphurization by semi dry preparation process and its application.

摘要

Nanomaterial adsorbent from waste from the system of flue gas desulphurization by semi dry, preparation process and its application.This invention describes the nanomaterial adsorbent and process for their production using waste from the system of flue gas desulphurization by semi dry generated in usiIn the coal power plant.The process for obtaining this nanomaterial adsorbent comprises the steps of reaction of residue from the system of desulfurization of flue gas (referred to by semi dry generated.M coal-fired plant mineral) with alkaline solution; heating the resulting mixture; separating solid and liquid of the suspension; washing and drying of the nanomaterial synthesis.The adsorbent has adsoru00e7u00e2o nanomaterial properties, properties cataliticas and high capacity of ionic exchange, allowing for varied applications.Being used in removal of toxic elements present in aqueous effluents.
