The analytical potential of solvent-assisted dispersive solid
phase extraction is presented and critically evaluated in this
article. The SADSPE allows the rapid extraction of cobalt(II),which
was selected as model analyte, using a low amount of sorbent
material (5mg). This method is environment friendly and robust
against very high contents of salt. The other benefits of the
method are its simplicity, ease of operation, good accuracy and
precision, short extraction time, low cost, and a good enrichment
factor. Although the obtained results in this work are related to
cobalt determination, the system could be readily applied for the
determination of other metals using various ligands. Future work
will be directed toward extending the method for the separation
and preconcentration of different inorganic and organic species
