Rapid and selective method for the spectrophotometric determination of nickel naphthenate in gasoline in a microemulsion

Add time:08/30/2019    Source:sciencedirect.com

A new method for the spectrophotometric determination of nickel naphthenate in gasoline in a microemulsion was developed. PAN reacts with nickel(II) forming a red complex with composition 1:2 (metal to ligand) nickel(II)-PAN and absorption maximum at 568 nm. Nickel naphthenate in gasoline can be determined with PAN in a microemulsion, in the pH range 3.0∼10.0 with a molar absorptivity of 4.8×104 l mol−1 cm−1. Beer's law was obeyed up to 0.8 mg l−1 of nickel(II) in the microemulsion system. The interference of Cu2+, Fe3+, Mn2+, Pb2+ and Zn2+ can be eliminated by adding 0.5 ml of a mixed masking agent. The method is rapid, simple and highly selective.
