Removal of cadmium by cementation with zinc powder is diffusion-controlled. This study analyzed the parameters that effective the removal of cadmium by zinc powder from the point of view of molecular diffusion. Studies have shown that parameter changes can be easily justified by this mechanism, and a logical connection is raised between the theoretical issues and what is happening in reality. https://jpst.irost.ir/article_1035_a34bacf839b923770b2c360eefa26748.pdf
