ABSTRACT:
This study presents a comparative evaluation of titrimetric and atomic absorption spectrophotometric (AAS) technique for the determination of calcium (Ca) and magnesium (Mg concentrations in table water sold in Okigwe own, Imo State, Nigeria. Calcium and magnesium are essential minerals that influence water hardness and have significant implications for human health and water quality. Samples of commercially packaged table water were collected from different locations within Okigwe town and analyzed using complexometric titration with ethylenediaminetetraacetic acid (EDTA) and atomic absorption spectrophotometry. The accuracy, sensitivity, and dependability of the outcomes from the two approaches were evaluated. The amounts of Ca and Mg observed in the water samples were assessed against World Health Organization (WHO) drinking water standards. Findings revealed variations in mineral content among the samples, reflecting differences in water sources and treatment processes. While the titrimetric method proved to be simple and cost-effective, the AAS technique demonstrated higher sensitivity and precision. The study concludes that although both methods are suitable for routine water abalysis, atomic absorption spectrophotometry offers superior analytical performance for trace metal determination. The results provide valuable information for water monitoring, public health assessment, and regulatory compliance in the packaged water industry.
