Abstract
We estimated the existence state and the amounts of potassium and bromide ion in salt crystal from the analytical results of solar salt imported and the samples washed.
The results were as follows;
1) It was estimated that potassium and bromide ion in solar salt were mostly included in salt crystal.
2) It was confirmed that 20 to 118ppm of potassium and 55 to 150ppm of bromide ion were included in salt crystal and those were different by the salt producing area.
3) Mole ratio of Br/K in salt crystal was higher than that in seawater.
