Abstract:  An infrared spectroscopic method for the determination of the composition of alginates has been elaborated. This method is based upon the determination of the ratio of absorbances of bands at 1320 and 1290 cm-1 (KBr technique, 1 — 2 mg of potassium alginate, analysis error ±3%), and 1125 and 1030 cm-1 (0.1 —0.2 mg of potassium alginate, analysis error ±8%).
