Ion-Exchange Batch Experiments for Heavy Metal Removal at Variable Salinity

A 2003 series of ion-exchange batch equilibrium experiments investigated the removal of heavy metals by Amberlite IRC748 resin under variable salinity and temperature conditions. The work was conducted by the Australian Antarctic Data Centre (AU_AADC) as part of project ASAC_1300, focusing on technologies for cleaning contaminated run-off from waste sites. Data is organized across multiple spreadsheets containing sample descriptions and raw experimental measurements.

Use Cases

• Modeling heavy metal adsorption efficiency (e.g., using 'Isotope' and 'Concentration AVG' columns) as a function of 'Seawater' salinity and temperature.
• Analyzing experimental quality control by comparing measured 'NIST' standard values against 'Ref Values' for calibration.
• Investigating contamination or carryover effects in sequential runs using data from the 'Rinse' column.
• Calculating removal rates for specific metals by analyzing concentration averages ('Concentration AVG') across different 'Sample' conditions and 'Dilution' factors.

Strengths

• Data includes controlled experiments at two distinct temperatures (4°C and 20°C), allowing for thermodynamic analysis.
• Incorporates quality assurance metrics through NIST standard references ('Ref Values'), in-house spiked standards ('QC'), and dilution blanks ('DilBlk').
• Measurements include corrected values ('Corr') for instrument drift, improving data reliability.

Limitations

• The exact number of experiments, rows of data, and complete column schema are unknown.
• Data is from 2003 and may not reflect current material performance or analytical techniques.
• Sample data is unavailable, making preliminary assessment of data structure and completeness difficult.
