Incorporating chemical and physical mechanisms into leaching models for solidified hazardous wastes Academic Article uri icon

abstract

  • Solidification is an important process for managing the disposal of hazardous wastes and will continue to be so until waste minimization and waste recovery processes are greatly improved. Solidification processes will continue to be needed because many wastes cannot be destroyed, and the mobility of hazardous components must be minimized before they are disposed in landfills. Although it is generally recognized that both chemical and physical processes are important in contaminant immobilization, most models used to describe leaching of contaminants from solidified wastes do not describe their effects separately. This paper describes how models for leaching can be developed that can separate the effects of chemical and physical immobilization processes. Analytical and numerical solutions are presented for a variety of systems, including those in which chemical reactions do not occur, in which linear sorption occurs, and in which nonlinear sorption occurs. 1989, All rights reserved.
