摘要：
The adsorption behaviour of pertechnetate on the anion exchanger Dowex 1-X8 was examined as a function of the acid concentration in the chloride, nitrate and perchlorate solutions at constant ionic strength. The distribution ratio decreases with an increase in the acid concentration. The distribution ratio of pertechnetate was also determined in the hydroxide system. The distribution ratio decreases with increasing temperature in all systems studied. At constant ionic strength, the distribution ratio of pertechnetate decreases in the order OH- > Cl- > NO3- > ClO4- and the relative selectivity coefficients for these anions were also determined.
