Activated Carbon for Operating Room Air Purification

In modern hospital cleanroom management systems, operating room air quality directly impacts patient post-operative recovery, infection risk, and the health of medical staff. Besides traditionally concerning particulate matter, bacteria, and viruses, volatile organic compounds (VOCs), residual anesthetic gases, disinfectant fumes, and rubber and plastic odors are also significant factors affecting the operating room environment. To achieve higher standards of air purification, acid-washed high quality coconut shell activated carbon has become an increasingly recognized solution in the industry.

Why choosing acid wash coconut shell activated carbon?

Coconut shell activated carbon itself possesses extremely high micropore content, excellent hardness, and stability, making it a long-standing user in air purification systems. High-end coconut shell activated carbon, after acid washing treatment, further enhances its application value:
• Removing inorganic impurities, reduces ash content, and improves air purification efficiency.
• Enhancing surface purity, making adsorption faster and more stable.
• Reducing the content of metallic impurities, avoiding potential interference with medical equipment.
• It is more suitable for high-cleanliness environments, such as operating rooms, ICUs, and sterile wards.

The acid washing process gives coconut shell activated carbon higher adsorption performance and better hygiene properties, perfectly meeting the stringent requirements of medical settings for "safety, stability, and no secondary pollution."

How does activated carbon work for air purification in operation room?

Gaseous pollutants commonly found in operating room air are often difficult to remove using physical filtration methods such as HEPA filters, while activated carbon is a key material for gas adsorption. Acid-washed coconut shell activated carbon achieves air purification primarily through the following methods:
Microporous adsorption: Its abundant microporous structure provides highly selective adsorption of small-molecule VOCs and anesthetic gases.
Surface adsorption: The acid-washed surface has more active sites, enabling more efficient gas capture.

Parameter of coconut shell activated carbon

Parameter	Typical Value / Range
Surface Area	1100–1250 m²/g
Iodine Value	1050–1200 mg/g
Pore Volume	0.50–0.60 mL/g
Ash Content	≤3%
Moisture	≤5%
Hardness	≥98%
Bulk Density	480–520 kg/m³
Particle Size	4×8 / 6×12 / 8×30 mesh

This type of activated carbon is particularly suitable for the following purification systems:
• Central air conditioning purification section in operating rooms
• Medical air purification units (including multi-stage filtration design)
• Anesthetic gas recovery/adsorption systems
• Local purification devices for high-cleanliness environments

Conclusion

Operating room air purification is not only crucial for patient health but also relates to the overall management level of the hospital. Selecting high-quality adsorption materials is a key step in ensuring air safety and cleanliness. Acid-washed coconut shell activated carbon, with its superior adsorption performance, stable physical strength, and high purity suitable for medical environments, has become the ideal material for medical air purification systems.
