Abstract:
Oral adsorbents used in the primary treatment of paraquat intoxication were studied in saline to evaluate their effectiveness in terms of removal ratio and removal rate.
Forty kinds of materials were tested as paraquat adsorbents.
Although cation exchange resin had the greatest removal ratio for paraquat, a high removal ratio was registered by an activated carbon derived from petroleum pitch. A significant correlation between removal ratio and the degree of crosslinkage in the resin was found.
The degree of paraquat concentration decrease was high when cation exchange resin was used. A significant correlation was found between the kinetic constant, which was calculated from the equation for a first-order reaction, and the degree of crosslinkage in the resin.
