PHOTOMETRIC DETERMINATION OF IRON (III) WITH SULFOSALICYLIC ACID

              The most prevalent element in nature is iron, which is also one of the essential, active macro elements. Today, photometric techniques are frequently employed to identify harmful and extremely poisonous heavy metals. Due to its sensitivity, simplicity, and short analysis time, this approach is extremely important. The technique of photometrically determining Fe (III) was devised, and the ideal conditions for the formation of a complex of Fe (III) with sulfosalicylic acid reagent were explored. The following steps were taken during the photometric determination of Fe (III) using sulfosalicylic acid: selection of a light filter, dependence of complex formation on environmental acidity, dependence on the composition of the buffer solution, dependence on the composition of the reagent, field of obedience to Ber's law, the ratio of the component moles of the complex, the Sendal sensitivity, the lowest detection limit of Fe (III), the molar extinction coefficient, and the technique of photometrically determining Fe (III).
