摘要: Manganese-doped zinc sulfide quantum dot based molecularly imprinted polymer composite nanoparticles were prepared. Bisphenol A served as the template and 3-aminopropyltriethoxysilane tetraethoxysilicane functional monomer cross-linker, respectively. The dots exhibited excellent selectivity, fast adsorption kinetics, high stability, good dispersion in aqueous media. quenched fluorescence emission was proportional to concentration of without any preconcentration. This highly selective sensor had a linear response from 10 700 nanograms per milliliter with correlation coefficient 0.9860. relative standard deviation five replicate measurements 100 2.2 percent. recovery fortified water samples ranged 98.70 105.50
