英文摘要 | Metal enhanced room temperature phosphorescence (MERTP) of fluorescein isothiocyanate isomer I (FITC) was observed with the presence of proper content of Ag@SiO2 core-shell (Ag@SiO2). The FITC-MERTP was quenched by the existing of lysine in the system. Based on this phenomenon, a novel method for determination of lysine had hereby been developed. Under the added amount ratio of FITC to Ag@SiO2 of 1: 1.5, pH of 8.0, the detection limit for lysine was 0.270 mu mol/L, the response was linearly proportional to the concentration of lysine in the range of 1.50-90.5 mu mol/L, the recoveries of standard addition of artificial samples were in the range of 97.0%-108.0%, the relative standard deviation was less than 2.1% (n= 9). A satisfactory result was obtained when the established method applied to the determination of lysine in compound lysine hydrochloride and zinc gluconate granules and lysine hydrochloride and calcium hydrogen phosphate tablets |
