Common salt is nothing but sodium chloride and its quality is determined by the sodium and chloride ions present. Besides human requirement of good quality salt, high purity salt is necessary for all kinds of heavy chemical industries which use salt as the basic material. The present study focuses on the chemical parameters of brine at various stages of different salt-pans of Kanyakumari district. The parameters included are percentage of chloride, sulphate, calcium, magnesium, sodium and potassium. The study revealed that the values of these parameters showed a marked variation in the different stages of the various salt-pans. The percentage of chloride, sulphate, magnesium and potassium were found to increase gradually from source to bittern stage but calcium and sodium showed a different trend. Calcium was found to increase from source to reservoir and then gradually gets decreased. Sodium gradually increased in the initial stages and in the final stage gets decreased.
