Embodiment Construction
[0014] In order to make the purpose, contents and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the examples.
[0015] The present embodiment proposes a preparation method of copper ion ferrous sulfide cleaning agent, the preparation method comprises weighing CuSO 4 ·5H 2 O; CuSO 4 ·5H 2 O was dissolved in deionized water and NH was added 3 ·H 2 O, to obtain ferrous sulfide cleaning agent. Soluble Cu is added to the cleaning agent 2+ , making it dissociate from ferrous sulfide (FeS) S 2- Generate CuS precipitates, Fe 2+ Fe(OH) is formed after hydrolysis 3 precipitation. In order to reduce the corrosion of the cleaning agent to the equipment, Cu in the solution 2+ The concentration cannot be too high, Cu 2+ The ion concentration is 0.01~0.02mol / L, add ammonia water NH to the cleaning agent 3 ·H 2 O, NH 3 ·H 2 O concentration is 0.1~0.2mol / L, a...
