研究了黑色食品的溶解方法,对不同的消解方法进行了对比试验,并对高压消解的最佳条件进行了探讨。建立了在H2SO4介质中,采用CTMAB-OP胶束增敏,锗-苯基荧光酮显色,并对最大吸收波长、显色时间、显色剂用量、酸用量、表面活性剂用量等影响因素进行了探讨。在λmax=507 nm,0～20μg/50 mL内符合朗白比尔定律,ε=1.31×105L.mol-1.cm-1。该方法具有良好的选择性、抗干扰性、重现性和稳定性,操作简单方便、无需分离,可直接用于黑色食品中痕量锗的测定。 The method of dissolving black food was studied, the contrast test of different digestion methods was carried out, and the best conditions of high pressure digestion were discussed. In H2SO4 medium, CTMAB-OP micellar sensitization and germanium-phenylfluorone color were used to determine the maximum absorption wavelength, color development time, the amount of developer, the amount of acid, the amount of surfactant and so on Discussed. In the range of λmax = 507 nm, 0 ~ 20μg / 50mL, the law of Lambert’s law was satisfied, ε = 1.31 × 105L.mol-1.cm-1. The method has good selectivity, anti-interference, reproducibility and stability, simple and convenient operation, without separation, and can be directly used for the determination of trace germanium in black food.
