抄録

An evaluation of adsorbent for the treatment of paraquat poisoning was performed. Forty kinds of materials (activated carbons, zeolites, molecular sieves, cation exchange resins, etc.) were used as removers, and the removal ratios and removal rates in vitro were discussed. The results show that cation exchange resin had a high removal ratio and rate. It was concluded that the removal rate of paraquat was mainly dominated by the degree of cross-linkage in the cation exchange resin. Moreover, it was found that cation exchange resins of the gel-type were more advantageous than those of the macroreticular type. Sodium polystyrene sulfonate, kayexalate, showed the greatest removal ratio and rate because of its great external surface area.
