Chemical and analytical properties of zeolite-containing rocks, poultry farm waste and their composite mixtures

Abstract

The comparative mineral composition of the zeolite-containing rock of the Terbunskoye field, poultry farm waste and composite mixtures with poultry farm waste has been carried out. The authors investigated the chemical and analytical properties of 3 variants of composite mixtures in relation to the waste of a poultry farm: zeolite - 45:55; 90:55; 180: 55. The method of spectrophotometry was the first to determine the chemical properties of zeolite samples and composite mixtures - antioxidant activity (inhibition of 0.025% DPPH solution, λ-517nm) in aqueous and alcoholic (carbinol) extracts; the sum of phenolic compounds (by the Folin-Chocalteu method, λ-750), and absorption spectra in the UV and visible spectral regions. The content of the main nutrients - Na, Mg, P, K Ca, Zn and Mo in the waste samples of the poultry farm is 15; 6, 21; 3.6; 14; 5.5 and 3.9 times higher, respectively, then in zeolite samples. And the use of composite mixtures contributes to the creation of fertilizers with specified parameters in terms of mineral composition.
