A calibrated Metrohm 780 pH-meter against standard buffer solutions, 4.00, 7.00 and 9.00 ± 0.01 was used to measure the pH-value of the examined sea water samples. Scanning electron microscope (JSM-6360LA, JEOL Ltd.), (JSM-5300, JEOL Ltd.) and an ion sputtering coating device (JEOL-JFC-1100E) were used to examine the images of deposited materials on the glass substrate.
