摘要:

Simple and sensitive spectrophotometric determination of palladium(II) withO-sulfophenylfluorone(SPF) was proposed in the presence ofN-hexadecyltrimethylammonium chloride(HTAC) as a cationic surfactant. The calibration graph was linear up to 1.2 μg/ml palladium(II) by measuring the absorbance at 585 nm against a reagent blank. The apparent molar extinction coefficient (ε) was 1.2 × 1051 mol−1cm−1and Sandell's sensitivity was 0.00096 μg/cm2palladium(II) at 585 nm. The effect of foreign cations or anions was partially examined.
