| 摘要 |
The process described concerns harmful substances which present a potential danger for the environment. They are neutralized by incorporating in the ground or ground-like material a reaction product, in the form of a preparation of hydrophobic solid matter, in order to undergo a chemical interaction with the harmful substance, thereby forming a water-insoluble reaction product. This preparation preferably contains the educt or reaction product of a dispersion-type chemical reaction. The educt for dispersion in a chemical manner can, for example, be in the form of calcium oxide or an aluminium alcoholate. For the chemical interaction, precipitation, condensation, polymerization, complexing or addition may be envisaged. The process according to the invention is also applicable in the case where the earth, contaminated by harmful substances, contains cohesive structures such as loam or clay, so that there can be no influence on the environment due to reaction bodies which have not reached an interaction. |
