The part of the diagram where the pH is greater than 9 or less than 4 was considered to be meaningless for the case study and the Eh of +0.4V and pH of 8 were assumed for seawater (Glasby and Schulz 1999). A solid phase preconcentration method has been developed using new chelating resin prepared by immobilization of 4-(2-thiazolylazo) resorcinol (TAR) on Chromosorb 106. 1). In order to provide reliable service performance of the material, this paper discusses its metallurgical properties, the relevant mechanisms of general, localized and erosion corrosion, the unique biofouling resistance and the performance in polluted water. We can derive the equation for es using two concepts you may have heard of and will learn about later: entropy and Gibbs free energy, which we will not go into here. Due to its biofouling resistance, the number of potential sites for pitting attack is limited, even in slowly moving seawater. The diagram is based on experimental corrosion data obtained in chloride solutions rather than thermodynamic calculations. As a basis to describe the salting-out rules and ore-forming trends of brine, the phase diagram graphically expresses the change law among components in a system. The sea-water solubility phase diagram is very complex since it involves almost all elements of the peri-odic classification and many compounds are observed during a crystallization sequence. During the cycle process, water is going through the changes and sometimes it can be solid like ice, liquid like water or as a gas like vapor.
