| Abstract | The purpose of this work was a study of influence of application of the most widespread and accessible methods of cleaning of humus matters from the admixtures of clay minerals. Small enough sizes and strong adsorption properties have clay minerals, which predetermine education durable organo-mineral colloid systems. Before research there was a task of cleaning of humus preparations from the admixtures of clay minerals. Scientists change the conditions of lead through such operations. As a result got humus preparations which differ in content of admixtures. Subsequent research of such preparations becomes complicated by influence of admixtures. FTIR spectroscopy is successfully used for the detection of content of clay minerals in soils and different functional groups in humus preparations. Three variants of cleaning of humus matters were probed. With the help of the method of FTIR spectroscopy was studied the quality of cleaning of humus matters from admixture by the methods of centrifugation, standing and ionic interchange. It is set that centrifugation on speed of 8000 turns in a minute within 10 minutes, purges humus solution from quartz and diminishes content of clay minerals, however in solution there are groups of Al–O–Si, Si–O–Si, Al–Al–OH and sulfates. Centrifugation and the use of the ionic interchange purge humus matters from clay minerals, sulfates, oxides of aluminum and silicon. | ||
