Abstract
Soluble and insoluble (suspended) organic matters of sea water, brine and bittern were studied.
(1) Nitrogen compounds were found to increase with increase in the chloride contents, and the increase in carbohydrate contents was much more, in the brine and bittern. Ratio of C:N was 7 to 8 in the suspended matters of sea water, but it increase to about 10 to 40 in the brine and bittern.
(2) H=49.3eE-37.0, where H is soluble organic matter contents (mg/L), and E is optical density at 463 mμ wave length.
(3) The suspended matter in the brine is found to be the cause of foaming.
