1. The molybdenum content of solar salts and home product salts were determined colorimetri-cally by the thiocyanate-stannous chloride method after being collected by adsorption with ferric iron and ammonia at the pH3-4.<BR>2. Analysis showed that the molybdenum of solar salt is distributed substantially in the insoluble matter, and that the mean content is about 0.03ppm, while, it is almost negligible in the water soluble part.<BR>On the contrary; in home product salts, the molybdenum is contained rather in water soluble part than in insoluble part, and is slightly much as compared with solar salt, unlike the case of another metals such as titanium, cobalt, nickel, chromium or vanadium.
