The Effect of Total Dissolved Solids (TDS) on SomePhysical and Chemical Properties of Some Water Samples

Abstract

   In this research paper, some of the physical and chemical properties of 12 water samples were studied. These included (6) samples from natural sources (Seawater, Man-Made River water, Groundwater, Zamzam water, Rainwater, and Qaber Aoun Lake water), and (6) samples from industrial (commercial) sources (Al Nabaa water, Shaima water, Hala water, Deiaffa water, Dajla water, and Distilled water). The refractive index (n), density (ρ), total dissolved solids (TDS), electrical conductivity (EC), and hydrogen ions (pH) were measured for all samples. The relationship between the values of total dissolved solids and the values of other properties was also established, and the extent of the influence of total dissolved solids on the values of the remaining properties was deduced. This study used the equipment available in the laboratories of the Physics Department at the Faculty of Science and the Office of Biological Research and Consultations at Misurata University.  The study demonstrated a strong direct relationship between electrical conductivity and other properties, some of which exhibited quasi-directional and some random relationships. The study also included a comparison between the obtained values and those published in previous studies, and demonstrated a high degree of agreement and consistency in the measurements obtained.
