Influence of red mud-N, P coated particles on micro-environment in contaminated ore soil
ADVANCES IN CHEMICAL ENGINEERING III, PTS 1-4(2013)
Abstract
In this research, improved granulation based on partly hydration of red mud was combined with gelling materials. Nitrogen and phosphoric salt were added in during granulation. Soil samples were collected periodically to evaluate the changes of pH, Z-potential and enzymatic activities of urease, catalase and alkaline phosphatase of soil. And the correlations among them were analyzed. Increase of pH that was caused by strong alkali was slowed by applying of composite particles. Dissolved phosphorus greatly inhibited all enzymatic activities while reinforcing restoration.
