The [Cs x Ba y] O 16 (0.,3, < x, y < 0.75) ceramics were designed for 137 Cs and 137 Ba immobilization, and they were synthesized by a solid-state reaction method. The raw materials were Cs 2 CO ,3,, ,BaCO 3,, Ti 2 O ,3,, and TiO 2, among which Ti 2 O ,3, was introduced to conserve the charge neutrality when Cs + ions were replaced by Ba 2+ ions.

BaCO 3 and Ba(OH)2 were used as precipitants and Ca(OH)2 was used for pre-treatment of mine water in the first step of experiments. The input values of mine water were: pH = 3.7 and SO42-= 2391 mg.l-1. In the second step only Ba(OH)2 and real mine wa-ter were used. The input values of mine water were: pH = 3.9 and SO42-= 2305 mg.l-1.

from mine water. The Ba salts commonly used for sulphates removal are BaCO3, Ba(OH)2 and BaS. Chemical treatment of mine water using Ba salts has proved to be capable of removing sulphates to less than 250 ppm [3]. Baryte (BaSO) is highly insoluble making it 4 an excellent candidate as removal phase for sul-phate treatment.

The ,BaCO 3, was reacted with phosphoric ,acid, to produce CO 2 [McCrae, 1950], which was analyzed in a modified Dupont 21‐491 dual‐inlet mass spectrometer. C isotope measurements are reported as δ 13 C values in per mil relative to VPDB, calibrated by analyses of NBS‐19 carbonate (+1.95‰) and normalized using equations and fractionation factors given by Coplen et al. [1983] .

solubility of relevant salts is as follows: MgSO4 >> CaSO4 > SrSO4 > MgCO3 > SrCO3 > CaCO3 > BaCO3 >> BaSO4 17, 18. Mg(OH)2 is also formed at high pH and is highly insoluble under those conditions. Precipitative softening with either lime or caustic soda has been widely used in produced water treatment for control of water hardness 4, 21-23.

This chemical precipitate was separated by filtration (0.45 μm, Sartorius, cellulose acetate). The solution was then adjusted to a pH of ,3,.0 by the titration with 0.1 M HCl solutions to induce degassing of CO 2, thus preventing from the precipitation of witherite (,BaCO 3,).
