Citric Acid Impregnated Activated Carbon Overview

Definition and Core Concept

Citric acid impregnated Aktivkohle is a special kind of activated carbon. It goes through a process that changes its surface. Citric acid is added to the surface during this process. This makes the material work better for cleaning water and air. The surface now has more places to trap unwanted things. Because of this, it can remove metals and organic matter more easily.

When citric acid is used, more active spots form on the carbon. These spots help the carbon grab and hold pollutants. The surface attracts copper ions and other harmful particles. You can use this activated carbon in many places that need strong cleaning.

Wesentliche Merkmale

Citric acid impregnated activated carbon is different because of its special features. The surface has more functional groups from the citric acid. These groups help the carbon catch and hold more pollutants.

Here are some important features to remember:

• Enhanced Adsorption: The changed surface helps the carbon absorb water and other things better. It works well for removing metals or organic compounds.

• Improved Water Absorption and Sorptivity: Tests show this carbon absorbs more water and has higher sorptivity than regular activated carbon. You can see this in the table below:

  Series	Water Absorption	Sorptivity
  Reference	Lowest	Lowest
  Citric Acid + Lime Milk	Highest	Higher than others
  Citric Acid + Glasswater	Similar to others	Varies with w/c ratio
  Higher w/c	Higher absorption	Lower sorptivity

• Targeted Pollutant Removal: This carbon can remove certain pollutants like copper ions and organic matter. The changed surface helps it focus on these targets.

• Sustainable Modification: Sometimes, waste materials are used in the process. This makes the carbon better for the environment.

• Vielseitige Anwendungen: You can use this carbon for water treatment, air cleaning, and in factories. The changed surface makes it useful in many ways.

Tip: For better cleaning, pick activated carbon with citric acid surface modification. The extra functional groups help a lot.

Surface Modification Process

Citric Acid Treatment Steps

Concentration and Application

You begin by soaking activated carbon in citric acid solution. Most people use a 0.3 M citric acid concentration for this. This amount changes the carbon’s surface in big ways. Using this level, the surface area of the carbon drops by about 34% to 38%. The smallest pores get smaller, but bigger pores get larger. This change helps the carbon trap certain pollutants better.

• The BET surface area goes down by about 14% after treatment.

• The BJH pore volume also gets smaller, but the carbon can now hold bigger molecules.

• The new surface has more active spots for catching pollutants.

Materials Used

You need activated carbon and citric acid for this process. You can use either granular or powdered activated carbon. Citric acid is the main chemical for changing the surface. Sometimes, other chemicals are added to help, but citric acid is most important. You soak the carbon in the citric acid, then heat it to help the change happen. After that, you wash and dry the carbon to finish the process.

Sustainable Sources

Citric acid impregnated activated carbon can be made from waste. Many companies use old food, like expired soda, white rice, or damaged buckwheat. These waste items have organic carbon, which works well for this process. You treat these materials with chemicals like potassium carbonate or orthophosphoric acid to make them better at adsorbing. This way, you recycle waste and help the environment.

Choosing sustainable sources helps the planet. The table below shows how different sources affect the environment:

• Biomass sources are easier to find and better for the earth.

• Activated carbon from biomass has less impact on the environment.

• Using renewable resources saves money and helps nature.

Tip: To lower your carbon footprint, choose activated carbon made from coconut shells or wood. These sources work well for citric acid surface modification and help keep the planet clean.

How Citric Acid Impregnated Activated Carbon Works

Mechanismus der Adsorption

Chemical Property Changes

When you treat Aktivkohle with citric acid, the surface changes a lot. The surface gets new chemical groups called carboxyl groups. These groups help the carbon pull in and hold pollutants. Adsorption happens mostly by chemisorption, which means strong chemical bonds form. More than one layer of molecules can stick to the surface. This process is fast and uses strong forces between molecules. The pseudo second-order kinetic model shows the adsorption is quick and strong.

Enhanced Pollutant Removal

Citric acid modification gives activated carbon a higher adsorption capacity. It can remove more pollutants, especially metals like copper, from water or air. The new surface lets the carbon grab copper ions much better. The carbon can hold up to 14.92 mg Cu/g, which is 140% more than before. Carboxyl groups make the bond with copper ions stronger. Even though the surface area drops by 34%, the carbon still holds more pollutants. The process is a little slower, but it removes metals and organic matter better.

Role of Citric Acid

Citric acid is very important in this process. It adds special groups to the activated carbon’s surface. These groups help the carbon catch heavy metals and organic compounds. You can see this when removing metals like chromium, copper, nickel, and zinc. At low pH, citric acid helps remove up to 100% of chromium and zinc, 98% of nickel, and 88% of copper. Lead removal also gets better, reaching 95% after 11 days. If you set the pH to 3, you can remove 100% of lead in just one day. Nickel and zinc removals are fast too, with 70% and 80% gone in two hours.

• Citric acid helps you target certain pollutants.

• The change makes Aktivkohle better for cleaning water and air.

• You get better results for heavy metals and organic matter.

Note: Using citric acid to change the surface gives you a strong way to clean up pollutants. This process helps your activated carbon work harder and adsorb more.

Comparison with Regular Activated Carbon

Surface Chemistry Differences

Citric acid impregnated activated carbon has a changed surface. Regular activated carbon does not have these changes. Scientists use tests like FT-IR and TPD to check the surface. The citric acid version has more oxygen groups. These groups help the surface react with acids and bases. There are more spots for reactions to happen. This helps the carbon grab metals and pollutants better. Regular activated carbon has fewer special groups. Its surface is more neutral and less active. Lab tests show these differences clearly.

Adsorption Efficiency

Citric acid impregnated activated carbon cleans better. The new surface groups hold metals and organic matter tightly. You get stronger bonds with copper and lead ions. Regular activated carbon can clean, but not as much. The citric acid surface boosts adsorption power. You can remove more pollutants with less carbon. This means water and air get cleaner faster.

Tip: Use citric acid impregnated activated carbon for tough jobs. It works better for heavy metals and strong organic compounds.

Application Performance
