Zusammenfassung:	FIELD: chemical technology. ^ SUBSTANCE: sample is subject to cleaning medium followed by inspection of cleaning hair from exogenous pollutions. Influence is carried out mechanically due to provision of high-speed vortex movement of sample in cleaning medium being chemically neutral to sample of hair. Degree of cleaning is checked due to estimation of non-transparency of cleaning solution. Water is chosen as cleaning reagent. Mechanical influence of cleaning medium onto sample is provided by means of mixer with two nozzles-blenders working at frequency of rotation within 1000 turns per minute. Turbidity of cleaning solution is estimated by turbidimetric method. Hair sample is subject to soaking before cleaning medium influences it. ^ EFFECT: higher quality of cleaning of terminal hair sample of cattle from exogenous pollutions; preservation of micro- and macro-element composition of hair. ^ 2 dwg
