Ether-Amine Adsorption Data for Iron Ore Flotation Wastewater Recycling

A study by Hana Dalila Fernandes investigated recycling ether-amines from iron ore flotation wastewater. The research achieved approximately 95% and 90% removal of ether-amines using Angelim sawdust and sugar cane bagasse, respectively, with adsorptive capacities of 4.2 and 2.7 mg.g-1. Thermodynamic studies indicated the process with sawdust was favorable and exothermic, and desorption tests showed the possibility of regaining around 80% of the ether-amines.

Use Cases

• Modeling adsorption efficiency based on pH, adsorbent type, and settling time mentioned in the description
• Comparing thermodynamic properties of different natural adsorbents for amine recovery
• Optimizing desorption processes to maximize ether-amine recycling rates
• Benchmarking flocculation versus adsorption methods for silica-amine separation

Strengths

• Reports specific removal efficiencies of approximately 95% and 90% for two adsorbents
• Provides concrete adsorptive capacities of 4.2 and 2.7 mg.g-1 for the tested materials
• Includes thermodynamic analysis stating the process is favorable and exothermic for one adsorbent
• Quantifies desorption potential, indicating around 80% of ether-amines can be regained

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment
