QUICK AND LOW COST SIMULTANEOUS SYNTHESIS OF SULPHUR DOPED CARBON DOTS (S-C-DOTS) FOR THE DETECTION OF FE3+ IONS AND ACTIVED CARBON (AC) FOR DYE ADSORPTION IN HIGH ACID ENVIRONMENT BY SIMPLE ACIDIC CARBONIZATIO OF SUCROSE.

摘要

An easy, facile, low cost and quick synthesis of sulphur doped carbon dots (S-C-dots) was carried out by acidic carbonization of sucrose (carbohydrate) without using any sophisticated instrument. The resultant S-C-dots shows excellent photoluminescent behaviour in highly acidic conditions with a quantum yield of 5.05%. Moreover, the as synthesised S-C-dots can be used as a dual probe for selective detection of Fe ions in highly acidic conditions by Fluorescence as well as UV-vis spectroscopy. Also, the residual waste generated during the synthesis of S-C-dots is used as an activated carbon (AC) for the application in dye adsorption from aqueous solutions.
