Abstract

The invention provides a ferromanganese cerium adsorption material for mercury removal. The ferromanganese cerium adsorption material is prepared from the following raw materials in parts by weight: 1to 6 parts of manganese acetate, 2 to 12 parts of cerous nitrate, 1 to 6 parts of ferric nitrate and 50 to 70 parts of deionized water. The invention also provides a preparation method of the ferromanganese cerium adsorption material for the mercury removal. The preparation method comprises the following steps: fully stirring and dissolving manganese acetate, cerium nitrate, ferric nitrate and deionized water, carrying out drying treatment, calcining, cooling and then taking out for rolling and sifting out to form the ferromanganese cerium mercury-removal adsorption material. The preparationmethod disclosed by the invention has the advantages of wide source of raw materials, simple and controllable process and mild operation conditions; the obtained ferromanganese cerium mercury-removaladsorption material has the advantages that the mercury removal rate can reach 90 percent or above under certain atmospheric conditions; in addition, certain high activity in a relatively long periodof time can be maintained, so that the ferromanganese cerium adsorption material for the mercury removal has a broad application prospect in the field of mercury pollution control.

Description

technical field [0001] The invention belongs to the field of material science, and relates to a mercury removal material, in particular to a manganese, iron and cerium adsorbent for mercury removal and a preparation method thereof. Background technique [0002] Mercury has the characteristics of persistence, mobility, high bioaccumulation, and strong toxicity. It is the only chemical substance among heavy metals that has an impact on the global scale. Environmental mercury pollution will cause great harm to human health. It is recognized as one of the world's top persistent environmental pollutants. [0003] At present, the activated carbon adsorption method is a mercury removal technology that has been widely used in recent years. However, due to the very large C / Hg ratio during operation, in order to obtain a certain mercury removal efficiency, the consumption of activated carbon is very large (without recycling), and the operating cost of mercury removal high. Selective...
