Scope
Aims, scope and focus
Separation Science and Technology is published by Taylor and Francis Ltd. and is in Zone 4 of Engineering in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Extraction and Separation Processes, Adsorption and biosorption for pollutant removal and Radioactive element chemistry and processing, together about 32.3% of its articles. Its main subfields are Water Science and Technology. (generated from OpenAlex topic counts and CAS ranking data)
This international journal publishes timely research on preparative separation processes and theoretical contributions to the field of separation science. We welcome papers on the following topics with applications across environmental sustainability, energy production, water treatment, and biotechnology: adsorption/absorption bioseparations centrifugation crystallization distillation electrically/magnetically driven separations flocculation extraction membrane processes precipitation reactive separations The journal is also interested in publishing papers on continuous separations, hybrid processes, and carbon capture. Numerical studies must highlight the broad applicability of the results beyond the system studied. The journal does not publish analytical separation papers unless they contain new fundamental contributions to the field of separation science. Separation requires a selective transfer (i.e. transferring one substance while rejecting another). Simply describing the transferring of one substance from phase A to phase B is not a separation. If selectivity is not demonstrated (or has already been demonstrated) the paper will not be considered for publication. Peer Review Policy: All submitted manuscripts are subject to initial appraisal by the Editorial Board, and, if found suitable for further consideration, to peer review by independent and anonymous expert referees. All peer review is single-anonymized. Publishing Ethics Statement: The Journal adheres to the highest standards of publishing ethics, with rigorous processes in place to ensure this is achieved. Taylor & Francis is a member of Committee of Publication Ethics (COPE) and utilizes Similarity Check via CrossRef for all journals.
