The interactions of rhein and emodin with TGA\u2010CdTe\/CdS QDs were evaluated by fluorescence and ultraviolet\u2010visible absorption spectroscopy. Experimental results showed that the high fluorescence intensity of TGA\u2010CdTe\/CdS QDs could be effectively quenched in the presence of rhein (or emodin) at 570\u2009nm, which may have resulted from an electron transfer process from excited TGA\u2010CdTe\/CdS QDs to rhein (or emodin). The quenching intensity was in proportion to the concentration of both rhein and emodin in a certain range. Under optimized conditions, the linear ranges of TGA\u2010CdTe\/CdS QDs fluorescence intensity versus the concentration of rhein and emodin were 0.09650\u201360\u2009\u00b5g\/mL and 0.1175\u201370\u2009\u00b5g\/mL with a correlation coefficient of 0.9984 and 0.9965, respectively. The corresponding detection limits (3\u03c3\/S) of rhein and emodin were 28.9 and 35.2\u2009ng\/mL, respectively. This proposed method was applied to determine rhein and emodin in human urine samples successfully with remarkable advantages such as high sensitivity, short analysis time, low cost and easy operation. Based on this, a simple, rapid and highly sensitive method to determine rhein (or emodin) was proposed.
