Development of optical sensor material for detection of cadmium using alizarin-red s indicator / Wan Elina Faradilla Wan Khalid and Nurul Farahidora Jaafar

In this study, Alizarin Red S (ARS) reagent was used to detect cadmium (Cd2+) in solution by using UV-Visible Spectrophotometer. Six parameters have been studied which are the effect of pH, effect of ARS concentration, photostability, linear range, reproducibility and interference study. ARS reagent...
