ABSTRACT:
Economical foams have been prepared from selected formulations containing whey solids, animal glue, surfactants, viscosity-builders, and activated charcoal. These foams are lightweight and act as carriers for the charcoal. Easy handling and dispersibility of the activated charcoal was accomplished by a combination of surfactants, either one being used as a wetting agent to control the activated charcoal and the other added to the remainder of the formulation. When applied broadcast on the soil, these foams are useful in removing from the soil residual toxic herbicides and pesticides which can cause significant damage to a sensitive succeeding crop.
