Adsorption properties of different polysaccharides on mercury in sodium chloride solutions solutions

The electrochemical method based on the measurement of alternating current (a.c.) in out of phase mode (expressed also as a capacitance ) at the hanging mercury drop electrode has been applied for the study of polysaccharides from different sources (microbial, algal). The difference in the adsorption behaviour is discussed in the relation to polysaccharides structural characteristics, as well as their molecular mass. Some of selected polysaccharides as well as natural seawater mucillage sample exibit also in phase - reduction wave at a potential of ~ - 1.35 V .
