    Conformational arrangement of humic particles in aqueous solutions

  • Original language description

    Conformational changes of humic acids in different aqueous solutions are studied by means of several methods. The method of ultrasound spectrometry is based on the measurement of parameters of ultrasonic waves propagating throughthe sample. The attenuation describes the decay of the amplitude of the ultrasonic wave with distance traveled. The velocity is the speed of this wave and is related to the wavelength and the frequency of oscillation of the deformation. It is determined by the density and elasticity of the sample, which is strongly influenced by the molecular arrangement. Mathod of dynamic light scattering provided data characterizing particle sizes and polydisperzity. Their combination with charge and rheological characteristics can give a complex description of conformational arrangement of humic particles in solutions.
