A method of removing fluoride impurities from trona and preparation of sodium bicarbonate |
| abstract |
The invention relates to a method of preparing sodium bicarbonate from trona containing sodium fluoride as an impurity comprising preparing a saturated solution of trona and filtering the trona solution to remove insoluble impurities; introducing carbon dioxide to the trona solution till the pH of the solution reaches the range of 7.5 to 8.75 and sodium carbonate in the trona solution is converted to sodium bicarbonate that precipitates; and recovering the precipitated sodium bicarbonate from the trona solution. |
