micro spectrophotometric determination and cloud point extraction of aspirin with iron (iii) in pure form and pharmaceutical drugs

Cloud-point extraction and molecular spectrophotometry in tandem was developed and suggested as a method for detecting aspirin and iron (iii) ions in pharmaceutical. in a dilute acidic medium, aspirin interacted with fe(iii) ions to produce a brightly colored [fe(iii)-aspirin] complex, which was originally as a mediated extractant, extracted into triton x-114 micelles, then determined by spectrophotometry at a wavelength maximum of 527 nm. for target analytes, all experimental variables were previously adjusted to accomplish this purpose. the results showed that pre-concentration factors of 80 for aspirin resulted in a detection limit of 0.23 g ml^-1 having a linear range of (5-120) gml^-1 (r= 0.9998). for aspirin, a mean recovery percentage of 98. ± 1.09% was recorded, with precision (rsd %) ranging from 0.04-0.66 %.
