In this paper, equations due to anion and cation distribution, velocity, electrical potential and shear stress profiles in a Nano channel have been investigated. These equations are employed in one dimensional electrokinetic flow. In the other word, governing equations have been solved by Homotopy Analysis Method (HAM). According to the literature, results have been compared with numerical solutions and it has shown that semi analylitical results have a very good accuracy
