X-Ray fluorescence
determination of bismuth in drugs "De-Nol" and "Vikalin"
Abstract
The principle
possibility of effective use of X-ray fluorescence analysis for determination
of bismuth contents in antibacterial drugs "De-Nol" and "Vikalin" is described. These drugs are used for treatment
of gastritis, gastric ulcer and ulcer ofdodecadactylon. The algorithm of calculation of
theoretical calibration function for X-ray bismuth determination in drugs is
offered. Proposed alternative way allows providing high accuracy of analysis
results without use of standards is shown. Adequacy of the developed approaches
is confirmed by results of titrimetric method of analysis.
Key words: theoretical
calibration function, drugs "De-Nol" and "Vikalin", bismuth determination.
