Embodiment Construction
[0023] The present invention will be further explained below in conjunction with specific embodiments.
[0024] refer to figure 1 , Example 1
[0025] In the present embodiment, a preparation method of a complex iron desulfurizer is proposed, comprising the following steps:
[0026] S1: Prepare the material of the complex iron desulfurizer. The material of the complex iron desulfurizer includes 31 parts of iron material, 42 parts of ethylenediaminetetraacetic acid, 13 parts of maltobiose, and 8 parts of polyethylene glycol monomethyl. Ether, 79 parts of mixed solution and 8 parts of modified additive, mixed solution includes two kinds of soda ash, ammonia water and caustic soda, modified additive includes cobalt salt and molybdenum salt, iron material includes iron salt, elemental iron ion, trioxide When one or two of iron and other iron-containing compounds, soda ash and caustic soda are mixed with ammonia water, the added deionized water accounts for 40% to 60% of the mixe...
