ADSORPTION ACTION OF BASIC ZINC CARBONATE ADSORBENT ON URANIUM IN NATURAL SEAWATER

1.The adsorption action of basic zinc carbonate adsorbent on uranium in natural seawater can be expressed with the following formula of adsorption isotherm:
C=k (U^*)n=8.51×10^-1 (U^*)0.49,
where C is the concentration of uranium on adsorbent; U^* is content of uranium in natural seawater employed.
2.when the quantity of basic zinc carbonate adsorbent (T) is constant, with the increase of natural seawater quantity through the adsorption column (G), also increased are the adsorption content of uranium of the adsorbent (U), the concentration of uranium on the adsorbent (C) and the concentration of residual uranium (C₀^*) in natural seawater after adsorbing uranium, while the rate of recovery of uranium (R) is decreased.With the increase of (G) the coefficient of distribution (K_d) decreases to a certain value and then a little rises again.
