Comparative study on salinity removal methods: an evaluation-based stable isotopes signatures in ground and sea water

Abstract This research aims to attain the optimal method of removing high salinity concentrations without its effect on balance or accuracy stable isotopes measurement deuterium and oxygen-18 (δ 18 O, δ 2 H). Four treatment methods (i.e., distillation, vacuum electro dialysis ion exchange) were applied for nine samples, which obtained from different water sources (sea, groundwater, river).l Worth notice that samples have Electrical Conductivity (EC) ranged (1000–60,000 µs/cm). Liquid–Water Isotope Analyzer used measure isotope concentration H. The findings four revealed their effectiveness with various percentages (normal distillation: 92.37%; 88.31%; dialysis: 94.85%; exchange: 99.62%). In addition, investigation was conducted a clear correspondence H) before after treatment. results indicated EC (1000–5000 µs/cm) no readings. Whereas, higher than 10,000, substantial influence Finally, distillation attained best among (10,000–60,000 affecting isotopic content There is measurements treatment, all selected samples.
