The interaction of organic materials with the surface reagents was studied. The optimum conditions of the reactions, quantitative characteristics of the composition and the surface compounds stability; the effective dates of the modified sorbents have been obtained. A new solid-phase spectrophotometric procedures was developed for determination of the organic materials organic materials in the objects.otherтвердофазное спектрофотометрическое определениеанализ объектовиммобилизованные красителианаліз об‘єктівтвердофазне-спектрофотометричне визначенняіммобілізовані барвникиimmobilized dyesanalysis of objectsinterface spectrophotometric definitionкафедра харчової хіміїOther
