A new micell-mediated phase separation technique has been created to preconcentrate levels of iron before measuring it using a UV-Vis spectrophotometer. The method is based on the extraction of iron from the 1-Nitroso-2- naphthol reagent using Triton X-114 in a cloud point extraction procedure, where the method's ideal conditions were attained. 0.2 mL of Triton X-114, 2.887 mmol. L-1 of 1-Nitroso-2-naphthol reagent, pH = 8, 60 ºC. The Iron detection limit for the method is 0.05 µg. mL-1, and the RSD% is 4.728 µg. mL-1. Linearity was maintained in the iron concentration range of 0.25 to 16 µg. mL-1. Furthermore, the interference impact of certain cations was assessed. The proposed method was successfully applied to determine the Iron ion in the wastewater in ten different stations. eight lifting stations and two treatment stations in the center and district of Al-Hurr in the Karbala city. In addition, the Iron element in the wastewater from the study sites was also directly evaluated using inductively-coupled plasma mass technology.
