Embodiment

[0024] First take 7.98g of anhydrous copper sulfate powder, configure 250ml of copper sulfate solution with a concentration of 0.2mol / L, then take 10ml of copper sulfate solution and 0.18g of Zn particles, the diameter of which is 2mm, and put them into a petri dish. The petri dish is placed in the magnetic field environment provided by the permanent magnet, the magnetic field strength is 500Gs, and the magnetic field gradient is 10T 2 / m. Another prepared exactly the same reaction system was placed in a non-magnetic field environment. Real-time photographing and recording of the reactions in the two environments, the results are as follows: figure 1 shown.

[0025] figure 1 It is the color change diagram of copper sulfate solution with or without magnetic field. The left side is without magnetic field, and the right side is with magnetic field. The blue is the color of Cu ions. The color becomes lighter, which means that the copper ions are replaced and the concentration i...

Abstract

The invention discloses a method for regulating a replacement reaction in a solution by a magnetic field. When a replacement reaction is generated in a solution, a magnetic field is extra added. According to the method, a magnetic field is extra added when a replacement reaction in a solution is generated, the potential difference between two reacting materials can be changed, and diffusion of ions in the solution toward a metal element can be influenced, so that the progress of the replacement reaction in the solution can be regulated. Time required by a replacement reaction in a solution can be greatly changed by utilizing an additional magnetic field under a condition of certain temperature. The method has a huge benefit value for reducing the reacting preparation cost, and accords with current development theme for saving energy and protecting environment.

Description

technical field [0001] The invention relates to the field of chemical replacement reactions, in particular to a method for regulating and controlling the replacement reactions in a solution by a magnetic field. Background technique [0002] The replacement reaction is a chemical reaction in which a simple substance reacts with a compound to form another simple substance and compound. It is one of the four basic reaction types in chemistry and covers a wide range of chemical fields. Among them, the reaction between simple metal and acid solution, or metal salt solution is more It is widely used in industrial production and environmental protection. For example, industrial copper smelting is a replacement reaction between iron and copper sulfate; heavy metal mercury ions in the environment are extremely toxic to the human body, and iron filings are often used to remove toxic mercury ions in wastewater treatment. Due to the limitations of the activity, morphology and solution ...
