Graphene-Based Adsorbents

Description

Product Overview
Graphene-Based Adsorbents are next-generation, high-surface-area carbon nanomaterials engineered for the selective removal of heavy metals, organic pollutants, and industrial contaminants from liquid and gas streams. Primarily used in water treatment, air purification, and chemical processing, these adsorbents deliver up to 10x higher adsorption capacity than activated carbon or clay-based media. Their strategic importance lies in enabling industries to meet tightening environmental regulations while reducing total cost of ownership through faster kinetics and lower sorbent mass requirements.

Competitive Advantage Spotlight
Unmatched adsorption capacity, ultra-fast equilibrium (minutes vs. hours), reusable via mild regeneration, and stable performance across pH 3–11.

2. Key Specifications & Technical Characteristics

• Chemical composition: Few-layer graphene oxide (GO) or reduced graphene oxide (rGO), surface-functionalized with carboxyl, hydroxyl, and epoxy groups

• Purity level: ≥99.5% carbon basis (metal impurities <0.05%)

• Physical characteristics: Black powder or pelletized form; typical particle size D90 < 20 µm (powder) or 0.5–2 mm (pellets); surface area 500–800 m²/g (expandable to 1,200 m²/g on demand)

• Bulk density: 0.08–0.12 g/cm³ (powder); 0.35–0.55 g/cm³ (pellets)

• Packaging options: 1 kg, 5 kg, 25 kg foil-lined bags; 200 kg fiber drums; 1 MT bulk bags

• Shelf life: 24 months in sealed, dry, cool (15–30°C) storage; avoid UV exposure

3. Core Industrial Applications

• Primary industries: Industrial water treatment, mining & hydrometallurgy, chemical & petrochemical, pharmaceutical manufacturing, air filtration (VOCs & mercury)

• Operational use cases: Removing lead, cadmium, arsenic, or chromium (VI) from wastewater; capturing oil/organic solvents from produced water; polishing high-purity process streams in semiconductor fabrication

• Performance advantage: Achieves >99% contaminant removal at initial concentrations up to 1,000 ppm; regeneration through pH shift or thermal treatment (150–200°C) allows 10+ reuse cycles with <15% capacity loss

• Cost/efficiency benefit: Requires 80% less adsorbent mass per cubic meter treated than granular activated carbon; lower disposal costs and smaller filter vessel footprint

4. Competitive Advantages

• Quality consistency: Lot-to-lot Raman ID/IG ratio variation <±0.05; each batch certified via ICP-MS, BET, and TGA

• Supply reliability: Redundant production lines across two continents; safety stock of 50+ MT maintained

• Logistics capability: Expedited air freight (5–7 days) or sea freight (20–30 days) with real-time tracking

• Price competitiveness: Tiered pricing from $85–250/kg based on purity, form, and volume; 30–40% lower than specialty resin alternatives on normalized capacity basis

• Sustainability: Fully thermally regenerable; spent adsorbent can be downcycled into graphene-enhanced composites

• Technical support: Full SDS, TDS, and application-specific dosing protocols; onsite pilot testing available for orders >500 kg

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 5 kg (sample-grade); 200 kg (commercial-grade)

• Bulk 20MT loading capacity: 20 metric tons (20,000 kg) per standard 20-foot dry container, palletized stacked in 1 MT bulk bags

• Loading per container (pellets): 22 MT per 20-foot container (marginal density advantage)
