✦ Synopsis

Detailed measurements of vapour breakthrough in activated carbon beds have been made for dimethyl-methylphosphonate (DMMP) and n-amylacetate. The measurements have been interpreted in terms of rate constant and adsorption capacity. The breakthrough curve follows the theoretical predictions at low output concentrations, but deviates at high concentrations. The rate constant is found to be very dependent on air velocity and grain size of the carbon. In the case of humid carbon and humid aid, the rate constant decreases, while the adsorption capacity is very little influenced by humidity.
