The object of this study was to determine change of natural buffer capacity of humic acids by strong buffering agents, which were phosphate ions. Studies were carried out on the humic acids extracted from peat soils. Additional information was obtained by determination of water holding capacity, density, ash and pH for peats and optical parameterQ4/6 for humic acids. Humic acid suspensions exhibited...
Celem niniejszej pracy jest optymalizacja procesu miareczkowania kwasów huminowych w obecności silnie buforujących jonów fosforanowych. Analizą optymalizacyjną objęty został zarówno sposób przygotowania próbek, kalibracja aparatury badawczej, mająca na celu ustalenie odpowiednich parametrów technicznych procesu miareczkowania potencjometrycznego, jak również otrzymanie wiarygodnych i powtarzalnych...
