Description
Pyridine-triphenylborane (PTPB) is one of the alternative tin-free antifoulants in marine antifouling paints and has been used widely in commercial copper-free self-polishing antifouling paints in Japan. Analytical method for determination of PTPB at low parts per billion (ppb) level in seawater has been developed by high-performance liquid chromatography (HPLC) with UV detection at 220 nm after pre-concentration with C18 solid-phase extraction (SPE). PTPB leached from an antifouling paint film was extracted from artificial seawater using a C18 solidphase extraction (SPE) cartridge, and eluted with acetonitrile/pyridine (99 : 1). The recoveries of PTPB (25μg/l and 50μg/l) spiked into artificial seawater were 96% and 97%, respectively. The limit of determination of PTPB using 100ml of artificial seawater was 0.5μg/l for this analytical method. The HPLC-UV using SPE was applied onto measurement of the release rate (μg/cm2/day) of PTPB from copper-free antifouling paints containing PTPB according to both ISO 15181-1 and 15181-2.
