Product Description
Product Introduction
Sphelite ACD-800B is a macroporous chelating resin on a styrene-acrylonitrile copolymer matrix whose grafted functional groups selectively bind gallium ions (Ga3+) by chelation. The resin is designed for alkaline elution circuits: a mixed Na2S·9H2O and NaOH regenerant strips gallium, followed by a 5.0mol/L NaOH activation step that restores the chelating groups for the next loading cycle.
Technical Indexes

Regeneration Cycle
- Mixed eluent: 4~6BV of 0.8333mol/L Na2S·9H2O + 2.5mol/L NaOH.
- Activation: 2BV of 5.0mol/L NaOH.
- Flowrates: 1-1.5BV/h for the mixed eluent, 2BV/h for water and NaOH.
- Rinse with 2~4BV pure water twice before elution and prior to NaOH activation.
Operating Conditions
Pre-treatment: Rinse resin with 1-2BV pure water.
Adsorption Conditions: SS ≤ 1 ppm.
Regeneration:
- Regenerants: 4~6BV mixed solution (0.8333mol/L Na₂S·9H₂O + 2.5mol/L NaOH) and 2BV 5.0mol/L NaOH
- Concentration: 0.8333mol/L Na₂S·9H₂O + 2.5mol/L NaOH, 5.0 mol/L NaOH
- Flowrates: 1-1.5BV/h (mixed eluent), 2BV/h (water & NaOH)
- Rinse resin with 2~4BV pure water twice before elution and prior to NaOH activation
Key Applications
- "Ga" extraction from Bayer-process alumina mother liquor
- "Ga" recovery from alkaline sodium aluminate liquor
- "Ga" enrichment from various alkaline liquid systems
Storage Proposal
The storage temperature of this material shall not be higher than 90°C. Stored above 0°C in wet state. In the storage state, keep the package sealed well to prevent water loss. In case of water loss, soak the dry resin in ethanol for about 2 hours, wash it with clean water and then repackage or use it. Prevent the spheroid from freezing and cracking in winter. If freezing is found, melt slowly at room temperature.
