Can sea water be disinfected?

In life, many people will find that they are receiving saline solution when they are receiving an infusion. The main ingredient in saline solution is sodium chloride. Since seawater contains more sodium chloride, everyone believes that seawater also has anti-inflammatory effects. When you are injured overseas and there is no way to treat the wound in an emergency, you will choose to use seawater for disinfection. In fact, there are also bacteria in seawater, so can seawater be disinfected?

Seawater contains a lot of sodium chloride. When bacteria are in seawater, the concentration outside the bacteria is higher than the concentration inside the bacteria. The water inside the bacterial cells is left outside, causing them to dehydrate and become inactivated. This is the same principle as the separation of plant cell plasmolysis.

It can still be disinfected. It has an effective effect. There are trace elements such as sodium chloride and magnesium chloride in seawater, but there are no disinfecting substances, so it can be disinfected.

Seawater is flowing, and the amount of water available to humans is unlimited. Seawater is a veritable liquid mineral deposit. On average, there are 35.7 million tons of minerals in every cubic kilometer of seawater. Of the more than 100 known elements in the world, 80% can be found in seawater. Seawater is also the source of fresh water on land and a regulator of climate. Every year, 4.5 million cubic kilometers of fresh water evaporates from the world's oceans, 90% of which returns to the ocean through rainfall, 10% falls on the land as rain or snow, and then returns to the ocean along rivers. Seawater desalination technology is developing into an industry. Some people predict that with the deterioration of the ecological environment, the last way for humans to solve the water shortage may be to desalinate seawater.

Seawater is a very complex multi-component aqueous solution. Various elements in seawater exist in certain physical and chemical forms. The existence form of copper in seawater is relatively complex, and most of it exists in the form of organic complexes. Among the free ions, only a small part exists in the form of divalent positive ions, and most of them appear in the form of negative ion complexes. Therefore, free copper ions only account for a small part of the total dissolved copper. Sodium is extremely abundant in seawater, but its chemical behavior is very simple and it exists almost entirely in the form of Na+ ions.

The dissolved organic matter in seawater is very complex, mainly a substance called "marine humus", whose properties are similar to humic acid and fulvic acid produced by the decomposition of vegetation in the soil. The molecular structure of marine humus has not been fully determined, but it can form strong complexes with metals.
