How does high-temperature alumina absorb toxic substances in water?

High-temperature alumina is very good at water treatment and can absorb a lot of toxic substances in water. How does it do this? Simply put, it is like a super magnet, but it does not absorb iron, but bad things in water.

1.There are many small "hooks" on the surface of high-temperature alumina, which can hook harmful substances in water, especially those positively charged ions, because they are particularly compatible with the negatively charged "hooks" on the surface of alumina.

2. These harmful substances will drill into the alumina little by little, just like small insects crawling into a hole. Once they drill into the alumina, they are firmly trapped and cannot get out.

3. In the adsorption process, the size of the alumina particles also depends on the size of the alumina particles. The smaller the particles, the faster they absorb, because it has more surfaces for people to "hook". But if the particles are too small, it will not work, and it is easy to block the pipe. Moreover, alumina must be "activated" first, just like a mobile phone needs to be charged before it can be used. Activated alumina has stronger suction and can absorb more.

Therefore,high-temperature alumina is particularly useful in wastewater treatment, and can remove heavy metals, pesticides, and some organic pollutants in the water. It is like an environmental superhero, protecting our water source from pollution.
