Abstract

A novel spectrophotometric method for the determination of aluminum (III) in aqueous samples was developed, validated, and optimized, based on the complex formation, between the analyte and Chromo azurol S using flow injection (FI) system. A five factor central composite design (CCD) using the response surface methodology (RSM) was employed to optimize the experimental reaction variables. The resulting second order polynomial model was found to be highly statistically significant, cofirming its excellent fit to the experimental data. Under the optimized conditions, the method demostrated satisfactory accuracy and precisión. The method s robustness was confirmed using a Youden-Steiner test, and was successful applicated and validated to tap wáter samples. The FI method shows advantages over the batch conventional operation, such as high sensitivity, low volume simple consumption, and high sample throughput (40 samples hr -1). Also achieved a high analytical GREEnness metric (AGREE) and blue applicability grade index (BAGI), which confirms its ecological quality and practicality. This work provides a rapid, cost-effective, and reliable analytical tool for the determination of aluminium in aqueous matrices.
