Pure iron is used as an additive for food and drugs to provide the human body with an important element which is iron. For this purpose, iron should be pure and in powder form, the extraction process can supply this type of iron. In this study, extraction of iron from an aqueous solution was done by cyclohexanone as an extractant. The parameters of extraction and stripping processes were studied and assessed the best values which give a high yield of separated iron from ore or any source of iron. For the preliminary study, three general parameters were studied and the best values are agitation time (10 min.), agitation speed (400 rpm), and temperature (30C). In the main study for the extraction process, there are four parameters were investigated and the optimum values are phase ratio (O/A) (1/1), iron concentration (conversely relationship), extractant concentration (proportional relationship), and normality (5 N). The best values for stripping process parameters are phase ratio(A/O) (1/2 – 1/1) and normality of strip solution (0.1 N).  The extraction technique is very important in Pharmaceutical industries to produce different suitable metals associated with food and drugs. The extraction technique was detected as an appropriate method to separate iron and introduce it in pure powder form.

The photochemistry of chelate complex 2-(6-methoxynaphthalen-2-yl) propanoic acid iron (III) Fe(L)3 was studied in three polar aprotic solvents: Dimethyl sulfoxide (DMSO), Dimethyl form amide (DMF), Acetone (Ac). Monochromatic light of wavelength 311 nm was utilized for the irradiation-process at 25oC. UV-VIS changes demonstrated an intraoxidation-reduction response happening amid the photolysis of Fe(L)3 complex, with homolytic scission of Fe-L bond. Quantum yield (Qd), rate of photodecomposition and reactivity proportion (k2/k-1) was resolved in every used solvent. These values dependably increment as polarity of the solvent increments and take after the order: DMSO > DMF > Ac. The mechanism of photodecomposition of this complex under the connected conditions was proposed.
