This study presents the development and application of a thermally reduced graphene (TRG)-modified SiO₂-APTES composite for the extraction and preconcentration of cadmium (Cd (II)) ions from aqueous samples, with quantification by UV-Vis spectrophotometry. To enhance the selectivity of Cd(II) detect...
