SPECTROPHOTOMETRIC DETERMINATION OF FOUR NAPHTHALENE SULFONATES IN SEAWATER AFTER THEIR MOLECULARLY IMPRINTED STIR BAR SORPTIVE EXTRACTION

ABSTRACT A novel 1- naphthalene sulfonic acid (1-NS) molecularly imprinted polymer (MlP)-coated stir bar for sorptive extraction of four naphthalene sulfonates (NSs) from seawater samples was prepared. 1-NS was applied as template molecule. The extraction conditions, including pH, the absorption and...

The linear ranges were 5-250 μg L−1 for 3, 6-NDS-1-OH (1-naphthol-3,6-disulfonic acid), 2-NS (2-naphthalene sulfonate) and 1-NS and 10-250 μg L−1 for 5-NH2-1-NS (5-Amino-1-naphthalenesulfonic acid).
