Carbon Loading

We fabricated surface modified activated carbons covered with ion-selective polymer. These materials can be used as powerful dispersants and flow electrodes, and improved desalting efficiency by high carbon loading via electrostatic repulsion.

AbstractActivated carbon and silica gel adsorbents are commonly used as sampling agents in small glass tube products for work environment measurements of organic solvent vapor in air. In the measurements, extraction efficiency of organic solvent components from sampling agents is very important for accuracy of the determination. We have investigated the effect of two representative efficiency determination methods as established by the Industrial Safety and Health Act in Japan: the direct addition and phase equilibrium methods, using both of these adsorbent materials found in typical recent sampling tube products in Japan and four types of alcohol. The results indicate that the phase equilibrium method has a tendency to show slightly higher values compared with the direct addition method for each adsorbent. In addition, compared with silica gel, petroleum-based activated carbon can be a preferable sampling agent of alcohols in the extremely low concentration region, below approximately 10 ppm.
