Pertraction Data for Selective Cerium Recovery from Light Lanthanoid Nitrate Solutions

A 56.2 KB DOCX file authored by Mustapha A. Raji and last updated on 2026-05 03. The document describes experimental results on the selective extraction of Cerium(IV) from a synthetic light lanthanoid nitrate solution using di-(2-ethylhexyl) phosphoric acid as a carrier in a hollow fiber liquid membrane system. It examines parameters like comparative extraction tests, stripping, and mass transfer rates, reporting a mass transfer rate for Ce of 3.00 ± 0.1 × 10^6 m/s.

Use Cases

• Modeling mass transfer rates in membrane-based separation systems based on the described experimental parameters.
• Comparing the performance of D2EHPA as a carrier for light lanthanoid separation against other methods.
• Investigating the influence of distribution coefficient and viscosity on extraction rates as discussed in the description.
• Studying the stability and selectivity of membranes for rare earth element recovery.

Strengths

• Specific mass transfer rate for Cerium is provided (3.00 ± 0.1 × 10^6 m/s).
• The experimental parameters investigated (comparative extraction, stripping, mass transfer) are clearly stated.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data is contained in a 56.2 KB DOCX file, indicating a very limited scope, likely a research article or report rather than a large dataset.
