Colorimetric analysis for salicylate in urine: An experiment for nursing chemistry

Salicylate Detection by Complexation with Iron(III) and Optical Absorbance Spectroscopy. An Undergraduate Quantitative Analysis Experiment

“…This experiment describes the quantitation of salicylate in liquid face wash using visible spectrophotometry. A similar colorimetric method published in this Journal described the detection of salicylate in urine for nursing students (5). Here, we expand the application of visible spectroscopy to determine salicylate in commercial face wash products and also to investigate the nature of the colored product formed during the analysis.…”
