Study of the influence of some inorganic salts on the gelation process in the agarose – water system by the optical method


The influence of a number of alkaline salts (NaCl, KCl, CaCl2 and KBr) on the gelation processes in aqueous agarose solution was studied by spectrophotometric method. The results of the study show that different anions have different effects on the gel. Among the salts where the anion is stable, KCl has the least effect on the gel formation and gel melting temperature, and among the salts where the cation remains stable, KBr has the least effect. The detected patterns are related to the influence of these salts on the structures of water, the medium where the gel is formed. The influence of inorganic salts on the structure of water is explained by the ability of ions to polarize water, which depends on the size, charge and charges surface density of the ion.

Keywords: agarose, alkaline salts, arrival temperature, melting temperature, hysteresis
