Abstract
A new adsorptive stripping voltammetric method for the determination of trace ATP based on the adsorption of ATP-thorium(IV) complex on the renewable mercury film silver based electrode (Hg(Ag)FE) is presented. The effects of various factors such as: preconcentration potential and time, pulse height, step potential and supporting electrolyte composition are optimized. The calibration graph is linear from 2.5 nM (1.27 μg·L-1) to 130 nM (65.9 μg·L-1) for a preconcentration time of 30 s, with correlation coefficient of 0.999. For a Hg(Ag)FE with a surface area of 9.4 mm2 the detection limit for a preconcentration time of 120 s is 81 ng·L-1. The repeatability of the method at a concentration level of the analyte as low as 2.5 μg·L-1, expressed as RSD is 2.1% (n=5). The proposed method was successfully applied and validated by studying the natural samples with simultaneous recovery of ATP from spiked tablet samples. © 2014 The Authors. Published by ESG.
