FIELD: analytical chemistry.
SUBSTANCE: invention relates to analytical chemistry, namely to a reagent indicator paper for the determination of chloride containing a chromogenic indicator: a silver compound with a reagent, 1-(3-methylpyrazole-5-yl]-5-(benzthiazole-2-yl)-formazanyl-6-cellulose of the general complex formula
,
where Cell is cellulose.
EFFECT: increase in the expressiveness, sensitivity in a wide range of detectable chloride concentrations, while simultaneously improving the selectivity, simplicity and clarity of analysis, as well as the convenience of determining the chloride content in liquid media using various test forms of a new reagent indicator paper.
