RRR Process Methods

A complete summary of the different removal, reduction, and retardation (RRR) processes that affect the constituents in the leachate experiments is given in Table 23. 

SoU - Batch tests (tests on individual samples) are conducted with soil- 

Photolysis - Photolysis is pollutant oxidation induced by sunlight energy resulting in irreversible alterations of the molecules. Through photolysis, light can affect the chemical composition and toxicity of organic compounds that comprise the TOC leached from C R materials 

For example, polycychc aromatic hydrocarbons (PAHs) containing three or more rings are able to absorb radiation strongly in the UV-A (320-400 nm) and UV-B (290-320 nm) regions of the solar spectrum 

Volatilization - Volatilization is the process whereby chemical components in liquid and solid phases volatilize and escape to the atmosphere as gases (1-4).
