Abstract

The invention discloses a synthesis method of a bentonite loaded iron carbonyl adsorbent. The synthesis method comprises the following steps: dropwise adding a NaOH or Na2CO3 solution into a ferric nitrate solution under water bath stirring condition, aging a product after ending the dropwise adding, diluting hydroxyl, then adding bentonite powder, stirring and separating sediment, adding the solid part into a tetramethylammonium chloride solution, stirring, washing and drying; putting the dried product in a microwave oven and irradiating the product for 3-6 minutes by using microwave; and finally adding the product irradiated by the microwave into a lithium chloride solution, stirring, separating sediment, washing and drying to obtain the bentonite loaded iron carbonyl adsorbent. The synthesis method has the advantage that the microwave is used for decomposing interlayer organic matters and breaking a layer structure of the bentonite to form a sawtooth structure, so that hole diameter is increased, thereby effectively increasing the adsorption speed of the iron carbonyl.

Description

technical field

[0001] The invention relates to the field of new materials for environmental pollution control, in particular to a synthesis method of a bentonite-loaded hydroxyl iron adsorbent. Background technique

[0002] Eutrophic pollution is the pollution caused by the eutrophication of aquatic ecosystems. Eutrophication refers to the excessive growth of aquatic plants (phytoplankton algae, etc.) caused by excessive nutrients in the water body, especially the excess nitrogen and phosphorus, which affects the normal oxygen exchange between the water body and the atmosphere, and the decomposition of dead algae consumes a large amount of oxygen, resulting in The dissolved oxygen in the water body drops rapidly, the water quality deteriorates, and fish and other organisms die in large numbers, which accelerates the aging process of the water body. Elements such as nitrogen and phosphorus in wastewater have seriously polluted surface water bodies. To effectively remove ph...
