采用动态法测定了NKA树脂对水中碘的吸附能力;研究了浓度、pH和流速等因素的影响;并在解吸条件和效率等方面与离子交换树脂作了对比。结果显示,NKA树脂对碘的吸附能力低于阴离子交换树脂和活性炭,但高于XAD-4和H-107。然而,NKA树脂的解吸效率和解吸液浓度比阴离子交换树脂和活性炭高得多。
The kinetic method was used to determine the adsorption capacity of NKA resin to iodine in water. The effect of concentration, pH and flow rate on the adsorption of iodine was studied. The ion exchange resin was also compared in terms of desorption conditions and efficiency. The results showed that the adsorption capacity of NKA resin to iodine was lower than that of anion exchange resin and activated carbon, but higher than that of XAD-4 and H-107. However, the desorption efficiency and desorption concentration of NKA resin are much higher than that of anion exchange resin and activated carbon.
