Experimental assessment of ultrasound and EDTA effects on multi-heavy metal retention in f

Mahdie Yazdani's dataset from figshare, last updated May 2026, contains experimental results on treating simulated mine water. The 11.0 MB dataset likely includes time-dependent measurements of heavy metal retention (Pb, Zn, Fe) under varying operational conditions. The study investigated factors like draw solution concentration, pH levels, ultrasonic parameters, and membrane orientation.

Use Cases

• Modeling time-dependent heavy metal retention efficiency based on operational parameters like pH and draw solution concentration.
• Comparing the performance of continuous versus pulsed ultrasonication modes on membrane performance.
• Analyzing the relationship between membrane structural properties (crystallinity index, roughness) and filtration efficiency.
• Evaluating the effect of membrane orientation (active vs. support layer facing feed) on rejection rates for specific metals.

Strengths

• Includes specific quantitative results, such as a 42% increase in membrane crystallinity index from ultrasonication.
• Reports concrete measurements like glass transition temperature (62.75°C) and root mean square roughness changes.
• Experimental design covers multiple controlled variables: two EDTA concentrations, three pH levels, and two ultrasonic frequencies.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Data is from a simulated mine water experiment, which may not fully represent real-world industrial effluents.
• The dataset is relatively small at 11.0 MB, which may limit the scope of analysis.
