| Abstract: | In this study, the (5,10,15,20-tetrakis(4-methoxyphenyl)]porphyrinato)cadmium(ii) complex (Cd(TMPP)]) was successfully used as a modifier in a carbon paste electrode (CPE) and exploited for bisphenol A (BPA) detection. Analytical performance revealed two linear ranges from 0.0015–15 μM and 0.015–1.5 mM with a detection limit of 13.5 pM. The proposed method was implemented in water samples, which resulted in quantitative signals over the range 6.5–1000 μM with recoveries between 92.6 and 107.7% for tap water and between 96.6 to 106.0% for mineral water.In this study, the (5,10,15,20-tetrakis(4-methoxyphenyl)]porphyrinato)cadmium(ii) complex (Cd(TMPP)]) was successfully used as a modifier in a carbon paste electrode (CPE) and exploited for bisphenol A (BPA) detection. |
