Abstract
A method of detecting one or more heavy metals in a sample solution is provided. The disclosure includes adding a dye to the sample solution having the one or more heavy metals to produce a color mixture. Mesoporous TiONPs are added to the color mixture to preconcentrate metal-dye complex onto the surface of the mesoporous TiONPs. Presence of the one or more heavy metals is detected by change in color within about 30 seconds via a naked eye. The disclosure further includes a method of determining concentration of one or more heavy metals in a sample solution by absorbance.
