TiO2 preconcentration integrated with hydride generation-colorimetric system for the rapid and selective detection of Se(IV).
Selenium (Se) is an essential trace element for humans and the determination of Se(IV) in daily samples is of great significance. A low-cost, easy-used hydride generation-fluorescence colorimetric method was developed for the rapid and selective detection of Se(IV) using a silver-based metal-organic framework (Ag-PMDA)...
