摘要
将超声波震荡悬浮液进样技术应用于火焰原子吸收光谱法,成功的测定了钙镁片药剂中的钙镁含量,将试样悬浮于琼脂胶体中制成悬浮液,直接喷入空气-乙炔火焰,用标准加入法测定,并将与灰化法测定结果进行了比较,经t检验,在显著性水平α=0.05时两种方法无显著性差异,相对偏差小于1.0%,此法快速简单准确。
Will ultrasonic oscillations suspending liquid in the injection technique is applied in flame atomic absorption spectrometry,Successful determined the tablet calcium magnesium,calcium magnesium levels potion,Put the samples of suspended in AGAR colloid made suspension,Direct spray into the air-acetylene flame,Use standard addition method determination,And the method for determining with ash,the results were compared,By t-test,In significant level α=0.05 two methods,no significant differences,Relative deviation is less than 1.0%,This simple,accurate and fast.
