Abstract: A class of diffusion equation for dust plasma in atmosphere was considered. Firstly, we took a travelling wave transformation for equation, and turned into a travelling wave equation. Secondly, we introduced a functional,  set variation was zero, and determined the Lagrange operator. Then we constructed a generalized variational iteration and determined the zeroth order approximate soliton solution, and derived the any order approximate soliton solutions by iterative. Finally, we used the travelling wave transformation to obtain the any order approximate travelling wave solutions of the soliton for the original equation.

Key words: diffusion equation, plasma, atmospheric dust, travelling wave solution, soliton solution
