Abstract
A fluorimeter is developed, which provides sample pretreatment, preconcentration of analytes from natural waters on the surface of indicator cellulose matrices, and the simultaneous measurement of their fluorescence. The device employs a L-711UVC ultraviolet light diode and a Digital color sensor S9706 photodiode, which registers simultaneously in the red (615 nm), green (540 nm), and blue (465 nm) spectrum regions. The opportunities of the application of this fluorimeter have been shown by an example of determination of 1–100 μg/L Al(III) and 0.1–10 μg/L Be(II) and Ga(III).
