Physical study to convert alginic acid to its salts (sodium, calcium)

Abstract

A compound alginic acid and its salts are widely used in industry,it is used as gels. since the study in the liquid state for alginic acid and its salts has an extreme importance in the industrial, pharmaceutical and food products, the existence of a relationship between increased concentration of dissolved material in influencing the solution viscosity and change some characteristics in shell formed by salts alginit thickness. factor prominent and important to know the accuracy use in several areas, including insulating materials used in manufacturing dental industry. In this research alginic acid was dissolving in 50% ethanol by using calcium ions. where samples were obtained from alginate and containing (0.2-7%) of calcium, has also been studying the properties of hydrogels in samples calcium alginate. The purpose of this article is to develop the distribution of the melting of alginic acid, which is the way we have sought to achieve in this article.
