عنوان انگلیسی Assessment of Heavy Metal Concentrations in Water Purifier Devices in Rafsanjan City
چکیده انگلیسی مقاله Introduction: Heavy metals (HMs) are one of the most important and dangerous pollutants in water resources. This study aimed to determine the HMs concentrations in city water purifier devices or stations in Rafsanjan, Iran in 2022. Materials and Methods: This study was conducted descriptively and on a laboratory scale on the input and output of 16 city water purifier devices stations in Rafsanjan in the summer of 2022. Heavy metals and other metals including arsenic (As), lead (Pb), chromium (Cr), copper (Cu), zinc (Zn), iron (Fe), magnesium (Mg), calcium (Ca), sodium (Na), and potassium (K) were tested by inductively coupled plasma mass spectrophotometry (ICP-MS). Also, t-test statistical analysis was used by SPSS software. Results: The mean concentrations of HMs in the output of city water purifier devices for As, Pb, Cr, Cu, and Zn were ≤ 1, 2.84 ± 0.71, 8.48 ± 1.51, 2.51 ± 1.55, and 18.58 ± 9.24 µg/L, respectively. The difference between the output of water purifier devices and standard values ​​for As, Cr, and Cu was significant (p ≤ 0.001). Other metals concentrations in the output of water purifier devices for Fe, Mg, Ca, Na, and K were 0.03 ± 0.008, 6.72 ± 0.92, 8.38 ± 1.71, 64.11 ± 2.56, and 2.34 ± 0.08 µg/L, respectively. The HMs removal efficiency of city water purifier devices for As, Cu, and Pb were ≥ 99%, 83.33%, and 56.33%, respectively. Conclusion: The HMs removal efficiency of city water purifier devices stations in Rafsanjan City was appropriate due to the use of filters containing alumina and iron hydroxide media.
