An essential industrial chemical, phosphoric acid is used in fertilizers, food additives like soda and cola. They are formerly called carbonated drinks. The quality and safety of the product may be impacted by impurities, discoloration, and heavy metal contamination, which are obstacles in the production of high-purity phosphoric acid.
By efficiently removing impurities through adsorption, activated carbon plays a crucial role in the purification process. The application of activated carbon for phosphoric acid production has the best pore structure and surface properties.
Activated carbon is a type of carbon characterized by a highly porous structure. These pores help increase the surface area to absorb contaminants. This is made from natural sources like coconut shells, coal, and wood. The porous structure gives activated carbon a high ability to absorb. it is necessary to ensure that the carbon undergoes certain activation, such as thermal or chemical induction. This activation procedure enables it to increase its porous structure, which helps in enabling maximum capacity.
The importance of phosphoric acid purification
The purification process of phosphoric acid is critical and varies depending on quality. In food applications like soft drinks, preservatives, and colas. Even impurities can affect taste and safety, demanding ultra-high purity. For industrial uses, fertilizers and detergents, removing contaminants ensures better chemical reactions and prevents technical damages.
There is a high chance of issues in raising impure phosphoric acid, which are as follows:
- Dark Colouration: The residue from the organic sources makes products visually unappealing. Therefore, the activated carbon will make it appealing.
- Toxic: The collected residue may be toxic, which may pose serious health hazards.
- Sulphur compounds: Products smell like rotten eggs due to sulphur compounds in impure phosphoric acid. Additionally, they react with metal surfaces, causing corrosion that gradually affects pipes and storage tanks. Which will further turn to create so many problems.
Without proper purification, these impurities reduce product quality, create safety risks, and increase production costs.
This is why activated carbon plays a crucial role as a powerful adsorbent, it effectively removes these unwanted impurities, ensuring phosphoric acid meets strict industry standards for purity and safety. The right grade of activated carbon makes purification efficient, economical, and reliable.
How activated carbon works in phosphoric acid treatment
A. Adsorption Mechanism
Activated carbon’s porous structure traps organics, metals, sulphur, and impurities. They help remove impurities. By strengthening attraction for polar compounds and generating active adsorption sites, surface chemistry, including oxygen groups, improves pollutant removal, particularly in acidic environments like phosphoric acid.
B. Key Application
- The application of activated carbon is very productive in decolourization, helps in filtering, trapping dark-coloured impurities to give the acid a clean, clear appearance.
- It is applied to heavy removal. It safely captures toxic metals such as arsenic or lead, and ensures the acid is safe for food, drinks, and medicines.
- The activated carbon helps to remove leftover chemical substances, it prevents unwanted reactions, and keeps the acid stable for industrial use.
- Each kind of key application plays a core role in purifying the process, now let how all the processes are happening.
C. Methods of Use
Batch treatment : it is the method where the filteration happens in batches.
Continuous column filteration: A large scale plants are constructed. It is the professional and factorial process.
Regeneration options: it is the cost-saving for reusable option, carbon can be used
