Summary, etc. <p style="text-align: justify;"><span style="font-weight: normal; font-size: small;"><span style="font-family: &quot;times new roman&quot;, times;">In the present study, homogeneous liquid-liquid microextraction via flotation assistance method is described for preconcentration of trace amounts of Mn(II). 1-(2-pyridylazo)-2-naphthol (PAN) is used as a ligand. The enriched analyte in the floated organic phase has been determined by inductively coupled plasma-mass spectrometry (ICP-MS). In this work, low density organic solvent is used and there is no need of centrifugation. Several factors influencing the microextraction efficiency, such as pH, the amount of chelating agent, nature and volume of extraction and homogeneous solvents have been investigated and optimized. Under the optimum conditions, the linear dynamic range is 1.0-500.0 ng L<sup>-1</sup> with a correlation coefficient of 0.9998 and the detection limit of 0.1 ng L<sup>-1</sup>. The proposed method has been successfully applied for separation and determination of manganese in different water samples.</span></span></p>
