Yellow Opaque Spherical Particles Macroporous Chelating Resin ACD-800B Selective Enrichment Metallic Gallium Ions Adsorption

The ACD-800B is a large-pore chelating resin made of polystyrene and acrylonitrile copolymer. Its core lies in attaching functional groups with specific affinity and selectivity for gallium ions (Ga3+) onto the polymer backbone. Its working principle is not simple ion exchange but rather coordination chemistry (chelation), and it is mainly used for accurately enriching metal gallium ions from the alumina mother liquor prepared by the Bayer process at a low cost, with low energy consumption and high efficiency.

• Suspended solids ≤ 1 ppm
• Suspended oil ≤ 1 ppm

1. Install resin column (effective size: φ25mm * 300mm), transfer measured resin volume soaked in pure water into column
2. Resin filling volume: 25-30 mL (1/4 to 1/3 of resin column)
3. Activate resin: rinse with pure water until effluent is clear, then drain; immerse in 5.0 mol/L NaOH solution
4. Maintain 2-3 cm liquid level of NaOH solution above resin layer
5. Activation completes after 24 hours (resin volume expands to approximately 1.3 times)

• Operating flow rate: 1-5 BV/h
• Operating temperature: ≤ 40℃

• Maintain proper moisture content during storage; prevent resin from drying out
• If resin becomes dry, soak in saturated salt water for gradual expansion, then slowly dilute salt concentration
• Prevent freezing or overheating; optimal storage temperature: 5-40℃
• For temperatures below 5℃, use salt water soaking for freeze protection
• For temperatures above 40℃, store indoors in dark location
