Ion-Exchange Column Breakthrough Experiments for Heavy Metal Removal

Laboratory data from ion-exchange column breakthrough experiments investigates the removal of heavy metals by Amberlite IRC748 resin under variable salinity and temperature conditions. The dataset comprises at least 12 spreadsheets containing sample descriptions and raw analytical data. Work was conducted by the Australian Antarctic Division (AU_AADC) as part of project ASAC_1300, with data last updated in December 2004.

Use Cases

• Model breakthrough curves and adsorption capacity using raw concentration data from spreadsheets 6-12.
• Analyze the effect of temperature (4°C vs 20°C) on metal removal efficiency by comparing experiments in spreadsheets 1-2, 4, and 5.
• Assess analytical precision and instrument drift by examining 'Corr' (corrected for drift) data and 'Concentration AVG' fields.
• Investigate the impact of salinity ('Seawater' field) and buffer conditions on the ion-exchange process for specific 'Isotope's.

Strengths

• Experiments conducted under controlled, variable conditions including two temperatures (4°C and 20°C) and salinity levels.
• Data includes quality control measures like NIST standard (1640) reference values and in-house spiked standards (QC).
• Raw data is separated across multiple spreadsheets (6-12) for specific experimental runs.

Limitations

• Specific row count, column count, and total dataset size are unknown.
• Data is temporally stale, with the last update in 2004, potentially limiting relevance to current materials or standards.
• Sample data and complete column schema are unavailable, complicating initial analysis.
