The properties of the algal chemicals. I.‐the evaluation of the common british brown marine algae as a source of alginate

Abstract An investigation has been carried out to evaluate the common brown algae indigenous to Great Britain as a source of alginate. In particular, the viscosity of the sodium alginate from each species has been examined, and the effect on the viscosity of drying and bleaching has been studied. In an attempt to show that the alginates from the different species are essentially the same, specific rotations have been determined.
