摘要：

Sorption of various species of radioactive iodine from aqueous and gas phases on polymeric sorbents Styrosorb and Polysorb-1 was studied. These sorbents do not take up ionic species of radioactive iodine ( 131I- and 131IO3-) from aqueous solutions. At the same time, both sorbents take up 131I 2 from aqueous solutions at 25°C. At V/m = 500 ml g-1, the distribution factors Kd are ∼1350 and ∼590 ml g -1 with Styrosorb and Polysorb-1, respectively. These sorbents efficiently recover 131I2 from an air flow at 25C and flow velocity of ∼0.33 cm s-1. The sorption capacity of Styrosorb is approximately four times higher than that of Polysorb-1 and amounts to ∼97.0 mg of I2 per gram of sorbent. These data are consistent with the specific surface areas of the sorbents."
