METHOD FOR COULOMETRIC DETERMINATION OF CONTENT OF TANNING SUBSTANCES IN PLANT MATERIAL

摘要

FIELD: chemistry.;SUBSTANCE: method of determining content of tanning substances in plant material in terms of tannin via coulometric titration involves interaction of the analysed sample with a coulometric titrant - hypoiodite ions, wherein the titrant is obtained under defined conditions, and content of tanning substances in terms of tannin is calculated using a defined formula.;EFFECT: method enables to obtain more reliable results and requires less labour input.;3 tbl
