| Abstract: | The sulfate anion of concentrated sulfate brine was removed by calcium chloride. Some influence factors on rate of sulfate anion removal and Ca2＋ concentration were reasearched by single factor experiment and orthogonal experiment, including rate of calcium and sulfur, reaction time and termperature, sodium sulfate concentration. |
| Keywords: | ionic membrane caustic soda concentrated sulfate brine calcium method sulfate removal |
