【 摘 要 】

Colloidal suspensions near 100 {micro}g/L can be pumped from below ground. Designing injection solutions that optimally mobilize colloids in the field also promotes desorption processes. As an example, in manipulating chromium-containing colloids, injected sorbate also served to displace the ion exchangeable chromate load in that subsurface region.
