摘要:
A formulation for colorimetric determination of the concentration of cyanuric acid compounds, particularly in swimming pool water, comprises an aqueous solution of a stabilizer, monoethanolamine and a thymolsulfonphthalein compound which, in aqueous solution with monoethanolamine, will exhibit different characteristic color shades dependent upon the concentration of cyanuric acid compounds. The stabilizer is a water-soluble, ultraviolet light absorbing material which is a condensation product of a disulfonic acid derivative with stilbene, stilbyle or their derivatives.A method of testing for cyanuric acid compound concentrations is to mix the formulation with a sample of swimming pool water and compare the resultant characteristic color shade with a standard color shade.
