| Outline of Final Research Achievements |
A new desorption method of organic solvent from activated carbon for working environment measurement was investigated. Plural surfactants and builders were examined as composition of the desorption solution. Predetermined concentration of an organic solvent was spiked into activated carbon particles and desorption efficiencies were investigated. For isopropyl alcohol, desorption efficiency was more than 90% when two kinds of surfactants and citric acid were used as a desorption solution. On the other hand, the desorption efficiency was different in each production lot of the coconut-shell-activated carbon, and the desorption efficiency tended to increase with decreasing pH of the desorption solution. More continuous investigation is necessary because desorption efficiencies were generally low for many organic solvents.
