Abstract

A simple and rapid spectrophotometric method for salicylic acid (SA) determination was carried out based on the complexation. In this study, copper(II) acetate was used as a colour developer. SA formed a stable yellowish green complexation with copper(II) acetate at pH 6.8-7.7. The working dynamic range was 0.02g/l - 0.30g/l. It had a maximum absorption at 400nm and stable for more than 50 hours. The results were used to train an artificial neural networks (ANN) for forecasting purpose. The model scores a correlation and summation of squared error (SSE) skill of 0.9994 and 1.2006 × 10-4 g/l respectively for ten hidden neurons. The average.
