The PFAS Crisis: A Permanent Solution

High-performance BDD Electrodes for PFAS destruction are now the gold standard for treating water contaminated with “Forever Chemicals.” Per- and polyfluoroalkyl substances (PFAS) possess one of the strongest bonds in organic chemistry: the Carbon-Fluorine (C-F) bond. Traditional filtration methods like activated carbon merely capture these chemicals, leaving you with hazardous waste to manage. Our Boron-Doped Diamond (BDD) technology does not just capture them—it destroys them.

We provide advanced BDD Electrodes for PFAS treatment that utilize electrochemical oxidation to mineralize these toxic compounds into harmless carbon dioxide and fluoride ions. Whether you are engineering a large-scale wastewater treatment plant or developing high-sensitivity biosensors, our MPCVD-grown diamond offers the purity and durability required for this demanding task.

The Science: How BDD Destroys Forever Chemicals

The efficiency of our BDD Electrodes for PFAS relies on the generation of hydroxyl radicals (•OH). BDD has an exceptionally wide potential window (up to 3.0 V), which allows it to generate these powerful oxidants without decomposing the water itself too quickly.

When you apply a current to our BDD anode, the surface generates •OH radicals that attack the C-F bonds directly. This process, known as anodic oxidation, effectively “unzips” the PFAS molecule. Unlike other electrode materials that corrode under these high potentials, our chemical vapor deposition (CVD) diamond layer remains stable, ensuring consistent destruction rates over thousands of hours of operation.

Applications: Destruction vs. Detection

Our BDD Electrodes for PFAS are versatile, serving two distinct but critical roles in environmental engineering.

1. PFAS Destruction (Water Treatment)

For industrial wastewater, landfill leachate, and groundwater remediation, you need an electrode that can survive harsh conditions. We recommend our BDD on Niobium or Titanium substrates for these applications.

  • High Current Density: Capable of operating at >100 mA/cm² to maximize radical generation.
  • Robust Substrate: Niobium is self-healing and resistant to the high voltages required for BDD Electrodes for PFAS destruction.
  • Target Product: Boron-Doped Diamond Electrode on Niobium

2. PFAS Detection (Sensors)

Before you can treat the water, you must detect the contamination. BDD Electrodes for PFAS sensing require an extremely low background current to detect parts-per-trillion (ppt) levels. Our BDD on Silicon is the industry standard for electroanalytical sensing.

  • Low Noise: The high purity of our MPCVD diamond ensures a superior signal-to-noise ratio.
  • Inert Surface: Resists fouling from other organic matter in the sample.
  • Target Product: Boron-Doped Diamond Electrode on Silicon

Why MPCVD BDD is Critical for PFAS

Not all diamond is created equal. Many competitors use Hot Filament CVD (HFCVD), which uses tungsten filaments that contaminate the diamond matrix. For BDD Electrodes for PFAS, this metallic contamination is a failure point.

Metal impurities in HFCVD diamond catalyze unwanted side reactions and weaken the crystal structure, leading to delamination under the high stress of PFAS oxidation. Our Microwave Plasma CVD (MPCVD) process is filament-free, resulting in a pure, dense, and tightly adhered diamond layer. This guarantees that your BDD Electrodes for PFAS will last longer and perform more consistently.

Frequently Asked Questions

Q: Why is MPCVD better than HFCVD for PFAS treatment?
A: MPCVD produces a purer diamond crystal without metal contamination. This makes our BDD Electrodes for PFAS more stable at the high voltages required to break C-F bonds.

Q: Can these electrodes treat PFOA and PFOS?
A: Yes. Studies show that BDD Electrodes for PFAS can achieve near 100% mineralization of both PFOA and PFOS, as well as shorter-chain variants.

Q: What is the lead time for custom sizes?
A: Our standard lead time is 1 month unless otherwise stated. We can customize dimensions to fit your specific reactor or sensor housing.

Q: Do you offer bulk pricing for water treatment plants?
A: Yes. Please contact us for a custom quote if you require large quantities of BDD Electrodes for PFAS remediation projects.
