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.
