| titleOfInvention | Method for rapid determination of sulphur ions with nanogold as logic gate color developing probe |
| abstract | The invention discloses a method for rapid determination of sulphur ions with nanogold as a logic gate color developing probe. As thiourea can enable aggregation of a nanogold solution, the solution changes from wine red to blue, and sulphur ions can specifically inhibit thiourea from aggregating nanogold, variation of the solution color and ultraviolet absorption spectrum characteristics can be shown, so that the sulphur ion concentration can be determined. Thiourea can make the nanogold solution undergo aggregation and change the solution color from wine red to blue, while sulphur ions can specifically inhibit thiourea from aggregating nanogold, thus showing variation of the solution color and ultraviolet absorption spectrum characteristics. The limit of detection of visual observation is 4 micromol/L. The linear range of absorbance ratio determination is 2-9 micromol/L. After simple pretreatment, mineral water, tap water, river water, white grape wine, human urine and other actual samples can be subjected to sulphur ion content determination by the method. |
