Abstract

An absorption microspectroscopy system was developed for absorption measurements of a laser-manipulated individual microdroplet in water under an optical microscope. Absorption spectra of various sizes of individual tri-n-butyl phosphate (TBP) microdroplets containing zinc tetraphenylporphyrin (ZnTPP) were studied as a model. Absorbance of ZnTPP in the droplet was confirmed to increase linearly with the diameter of the droplet, showing that the Lambert-Beer law is followed for droplets with a diameter larger than 6 μm. The concentration of ZnTPP in the droplet dispersed in water is lower than that for pure TBP film by a fixed proportion, which was considered in terms of a constant water partition into TBP.
