ABSTRACT:
Processes for decreasing mercury butter formation in mercury electrolytic cells employing brine which contains strontium wherein the brine is treated to lower the strontium content to 0.5 ppm or less. The removal of strontium from the brine may be effected by treating the brine with an ion exchange resin in sodium form to adsorb strontium thereon. Alternatively, strontium may be removed by treating the brine with a water-soluble metal hydroxide, subjecting the resulting mixture to partial evaporation to produce sodium chloride as precipitate and saturated brine solution and admixing the precipitate with water to form brine for electrolysis.
