Ounifi et al. 2020 - Cellulose acetate cadmium remediation
Ounifi and colleagues evaluated cellulose acetate nanofiltration membranes for cadmium removal from model water. This is in-scope lane a2 remediation evidence and not food or salt occurrence evidence.
Key numbers
The introduction cites prior studies reporting cadmium concentrations up to 5 ppm in polluted water. The experiments tested feed concentrations from 10-4 to 10-2 mol.L-1 and transmembrane pressures from 2 to 14 bar.
The conclusion reports cadmium rejection up to 98% for the prepared cellulose-acetate nanofiltration membranes.
Methods (brief)
The study prepared cellulose acetate nanofiltration membranes and tested their hydraulic permeability and cadmium rejection under varying pressure, feed concentration, and ionic-strength conditions. Membrane performance and ion rejection were analyzed through the tables and discussion in the extracted PDF text.
Implications
Certification: Not product-occurrence evidence.
Courses: Useful membrane-remediation case for cadmium removal from contaminated water streams.
App: Context only.

Verification notes
Recovered from skip:not-food-occurrence under the 2026-06-10 inclusion-by-default rule. The old skip dropped the paper because it lacked finished-food numbers; on re-read it is in-scope lane a2 remediation evidence.
