Chemical Compositions of Persian Gulf Water Around The Qeshm Island At Various Seasons

Abstract

In this paper, the results of chemical analysis of Persian Gulf water around Qeshm Island in Strait of Hormuz, is reported. The water samples are taken from various beach places around Qeshm Island and at four different seasons for investigation of effects of place and season changes on water compositions. The total dissolved solids (TDS) at 105, 180 and 550 ºC were found as 43900-57550, 42507-53500 and 34830-47200 mg/L, respectively. The pH was between 8.01- 8.34 and the average density was 1.027 g/mL. Concentration of Ca²⁺, K⁺, Mg²⁺, Na⁺, Sr²⁺, Ni²⁺, Cl^–, Br^–, S²⁺, SO₄^2- and CO₃^2- determined as 316-678, 173-555, 1915-1341, 7646-9002, 5-6, 0.312-0.324, 20855-22720, 0.072-0.078, 575-1020, 1725-3060 and 154-160 mg/L, respectively. Some minor components such as Li, Fe, Zn, Mn, SiO2, Cu, Zr, Mo, V, Pb, Sn and Al were determined.
