МЕТОДЫ ОПРЕДЕЛЕНИЯ ИОНОВ СЕЛЕНА И ЦИНКА В ХЛОПКОВОЙ ШЕЛУХЕ И ШРОТЕ.

Background. In livestock farming, the balance of feed and diet, including macro-, microelements and vitamins, is important. This is facilitated by control of microelements in feed. Purpose. Determination of selenium and zinc content in husks and meal using SEM and X-ray fluorescence analysis. Methodology. SEM "JEOLJSM -- IT200 LA", X-ray fluorescence analyzer "SpectraXEPOSX-ray" and optical spectroscopy devices were used. Originality. Data were obtained to select the optimal method for detecting selenium and zinc in animal feed. Findings. The sensitivity of X-ray fluorescence analysis and SEM methods with respect to selenium and zinc in meal husks was revealed. A method for its enrichment with microelements has been developed.
