Graphene Oxide Adsorbent

Description

1. Product Overview

Graphene Oxide Adsorbent is a next-generation, two-dimensional carbon nanomaterial engineered for high-efficiency adsorption of ionic contaminants, heavy metals, and organic dyes from industrial wastewater and process streams. Its primary industrial use is in water remediation, hydrometallurgy, and pharmaceutical effluent treatment, where it outperforms conventional media through an ultra-high surface area (>600 m²/g) and oxygen-rich functional groups. The key value proposition is a >99% removal efficiency for contaminants like lead, cadmium, and methylene blue at half the dosage of activated carbon or zeolites. Strategically, it enables industries to meet stringent EPA and EU discharge regulations while reducing sludge disposal costs—making it critical for ESG-aligned operations.

2. Key Specifications & Technical Characteristics

• Chemical composition: Graphene oxide nanosheets (C:O ratio 2.1–2.4); oxygen functional groups (epoxy, hydroxyl, carboxyl)

• Purity level: >99% carbon basis; <0.5% ash content; heavy metals below ICP-OES detection limit

• Physical characteristics: Brownish-black powder; lateral sheet size 0.5–5 µm; thickness 0.8–1.2 nm; bulk density 0.08–0.12 g/cm³; specific surface area 600–750 m²/g (BET)

• Packaging options: 25 kg vacuum-sealed foil bags; 500 kg FIBCs (big bags); 50 kg HDPE drums with desiccant

• Shelf life: 24 months when stored below 30°C in airtight, dry conditions away from UV light

3. Core Industrial Applications

• Heavy metal removal (mining & electroplating): Lead, chromium(VI), arsenic, and cadmium in wastewater – achieves <0.1 ppm effluent limit with contact time of 15 minutes (vs. 60+ minutes for activated carbon).

• Pharmaceutical & dye effluent (textiles & API manufacturing): Methylene blue, tetracycline, and rhodamine B – >98% adsorption at pH 5–8 with no leaching of graphene into treated water due to proprietary cross-linking.

• Pre-treatment for desalination (power & water utilities): Removes organic foulants before RO membranes – extends membrane life by 300% and reduces chemical cleaning frequency by 70%, delivering a 6-month payback period.

4. Competitive Advantages

• Quality consistency: Lot-to-lot CV <3% for surface area and oxygen content, certified by ISO 17025 third-party lab reports included per shipment.

• Supply reliability: Dual manufacturing lines (Asia and EU) with 500 MT/month capacity; 48-hour dispatch for urgent orders.

• Logistics capability: UN-certified, non-hazardous classification (UN No. not applicable for dry GO); door-to-door DDP available to 50+ countries.

• Price competitiveness: $45–65/kg depending on volume – 20–30% lower than commercial alternatives at equivalent purity.

• Sustainability & documentation: Produced via low-waste Tour method (no explosive permanganate); full life-cycle assessment (LCA) and safety data sheet (SDS) in 12 languages provided on purchase.
