Abstract
A method for determining optical proline concentrations in samples of natural waters, based on the measurement value angle of the plane of polarization of radiation of a certain wavelength λ, which has been studied by the liquid thickness l = 5 sm was developed. Three wavelength λ = 400, 450, 500 nm were used. A series of reference samples was produced: aqueous solutions of L and D forms proline of a known concentration within c = (0.001 - 0,1) %. Based on these studies, for each λ gauge dependent quantities of angle α = f (c) was built. Using them and conducting measurements of angles α for the real natural environments, the possibility of determination of the concentration of proline in them was actualized. It was determined that in waters within the city of Chernivtsy and its surroundings occured proline of two forms: L and D, the concentration of which is within c = (0,005 - 0,094)%.
