“…Optimization of manifold parameters and experimental conditions were carried out by means of univariate method, 25 in which a variable was modified while maintaining the other variables at their constant values (selected by random). Then by maintaining that variable at its optimum value, another was modified and this procedure was repeated for all variables.…”

Abstract. A flow-injection spectrophotometric method is developed for determination of N-acetyl-Lcysteine (NAC) in pharmaceutical formulations. The method is based on coupled redox-complexation reaction, the first step of which is the reduction of Fe III by NAC; the second one includes the complexation of Fe . The analytical frequency was 60 h -1 . Usual excipients used as additives in pharmaceuticals do not interfere with the analysis of NAC. The proposed method is simple, rapid, sensitive, accurate and precise (repeatability RSD 0.29 %, n = 10), and can be applied for determination of NAC in pharmaceutical formulations up to nanomole quantity.
