Linear Approximation of Lambert-Beer′s Law and Its Application to Ultra-Micro Analysis by Atomic Absorption Spectrometry

Based on the Lambert-Beer′s Law and considering the determination of ultramicro amounts of substances by AAS,an approximate linear relationship between the transmittancy and concentration of the measured substance was derived.As shown by experimental results,by its application,the sensitivity of AAS was increased by 2 to 3 orders of magnitude.
