Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A potentiometric flow injection system was adopted by using a Li⁺‐selective electrode with improved selectivity for sensitive and selective determination of Li⁺ in human serum spiked samples. For the optimization of the offered flow injection system, multivariate method was utilized. Potentiometric characteristics of the system were investigated (linear range: 5.0×10⁻⁵−1.0×10⁻¹ mol L⁻¹, slope: 56.93 mV per decade, detection limit: 3.4×10⁻⁵ mol L⁻¹, sampling‐rate: 40 injections per hour). The detection of Li⁺ in real serum samples was achieved. The obtained results for the spiked serum samples were in good agreement with IC results at 95 % confidence level.</p> </abstract>
