В работе описаны исследования коагуляции в зеленом соку из люцерны при помощи нефелометра. Исследовались процессы коагуляции при pH натуральном и при pH, доведенном до 9,4, в диапазоне температур 20-85°С. Исследовательский материал получено во время сжима проб люцерны под соответствующей нагрузкой. Для выяснения проблематики коагуляции использовано методы статической физики. Полученные результаты указывают на изменчивость исследуемых признаков в зависимости от разных факторов.

The main aim of the paper was to study the effect of coagulation of copper ions on dissolved form of humic acids. Research material was isolated from four peaty muck soils (Terric Histosols). The soils were described by means of the Springer humification number, secondary transformation index, ash content and pH in H2O and in KCl. For the studied humic acids, surface charge was determined, E4/E6 which described the degree of concentration of the chain of aromatic carbons of the humic acids and could be used as their humification number, and the elemental composition and atomic ratios were determined as well. Systems composed of humic acids and increasing concentrations of copper ions were investigated at pH 5 and in the copper concentration range of 0-40 mg dm-3, at constant concentration of humic acids. Coagulation of solutions was studied by measurement of changes of organic carbon and copper ions concentration in liquid phase at pH 5 as well as by observation of absorbance changes at wavelength 465 nm in series of prepared solutions. The results showed that coagulation of experimental systems consisted mainly in humic acid coagulation. In a certain range of concentration of copper added to solutions, metal also partly precipitated and went to the solid phase together with humic carbon, which indicated coagulation of complexed compound of humic acids with copper. At high copper concentration, ionic strength had a dominant influence on coagulation of humic acids. Copper ions stayed all in liquid phase, whereas almost total organic carbon passed to precipitate, which resulted from interactions with electrolyte ions.
