Abstract:
The aims of this study were to evaluate the raw salt (Sodium Chloride (NaCl)) manufactured
at Port Sudan and to find the effect of purifying this raw salt to conform with the international
and Sudanese standards for table salt. Samples were taken from two factories: Baboud and
Rwaia which produce raw salt. The samples were analyzed to determine their quality. The
samples were then treated in the laboratory by washing with saturated solution of pure NaCl
to remove the impurities i.e. SO42-, Ca+2, Mg+2, CO32-, CL— etc. The treated samples
were analyzed and the results revealed that washing of the raw salt with brine must be adapted
for the salt produced in Port Sudan at different factories for it is contaminated with elements
that make it not conforming with the standard.
