The concentrations are varied from 0.3 - 1.0 x 10<sup>-1</sup> mol.l<sup>-1</sup>. The results showed almost constant on the partial molar volumes with increasing surfactant concentration. Also, the partial molar volumes are found to increase with increasing temperature over the entire concentration range investigated in a given mixed solvent medium and these values are found to decrease with increasing methanol content in the solvent composition.</p> <p><strong>Keywords: </strong>Mixed solvent; Cetyltrimethylammonium bromide; Surfactan; Partial molar</p><p>DOI: 10.3126/jncs.v24i0.2383</p> <p><em><strong>Journal of Nepal Chemical Society,</strong></em><em> </em>Vol. 24, 2009 Page: 24-30</p> <p><em> </em></p>}, journal={Journal of Nepal Chemical Society}, author={Shah, Sujit Kumar and Bhattarai, Ajaya and Shrivastav, Ghanashyam and Chatterjee, Sujeet Kumar}, year={2009}, month={Dec.}, pages={24–30} }
