Aluminium ions are proving to be a game-changer in the fight against water pollution. These ions, specifically metastable aluminium ions, are being used in a new process to break down oxytetracycline (OTC) in water. This process is a type of Fenton-like reaction, which means it uses hydrogen peroxide to create hydroxyl radicals. These radicals are highly reactive and can break down pollutants.

The process works across a wide range of pH levels, from 2. 5 to 12. 0. This is a significant advantage because it means the process can be used in many different environments. It also means that the ions do not form any solid waste, which is a common problem with other methods. This makes the process more efficient and environmentally friendly.

Under the best conditions, OTC can be broken down in just about 10 minutes. After 24 hours, more than 60% of the total organic carbon is removed. Even in a neutral solution, the process can break down about 80% of OTC. This shows that the process is effective in a variety of conditions.

One of the most impressive things about this process is that the aluminium ions can be reused. Even after six cycles, there is no significant decrease in their ability to break down OTC. This makes the process more cost-effective and sustainable.

The byproducts of the reaction have been identified. The process includes decarbonylation, hydroxylation, and dehydration. This means that the OTC is not just broken down, but it is also transformed into less harmful substances. This is an important step in making the process more environmentally friendly.

This new method offers a promising solution for removing OTC from water. It is efficient, environmentally friendly, and cost-effective. As research continues, it is likely that this process will become an important tool in the fight against water pollution.
