Optical sensing material based on hybrid sol-gel/pva for cadmium detection / Nurul Farahidora Jaafar

In this study, Alizarin Red S (ARS) reagent was used to detect cadmium (Cd2+) in free solution and immobilization form. For free solution, six parameters has been studied, effect of pH, effect of reagent concentration, photostability, dynamic range, reproducibility and interferences. ARS complex sho...
