Visualization of neuronal elements is of fundamental importance in modern neuroscience. Golgi-Cox impregnation is a widely employed method that provides detailed information about morphological characteristics of neurons, but none regarding their neurochemical features. Immunocytochemical procedures, on the other hand, can

Adsorption thermodynamic characteristic and kinetics of dissolved chromium from aqueous solutions onto humic acids (HAs) were studied. The results showed that the Freundlich isotherm model described the equilibrium data well. The negative DeltaG degrees confirmed the spontaneity of adsorption process.
