Determination of cyanuric acid in swimming pool water by differential pulse polarography

RETRACTED: Adsorption of cyanuric acid on activated carbon from aqueous solution: Effect of carbon surface modification and thermodynamic characteristics

“…Various analytical techniques such as titrimetry [3], turbidimetry [4], colorimetry [5], pulse polarography [6], gas chromatography (GC) [7], high-performance liquid chromatography (HPLC) [1,2,4,[8][9][10][11] have been investigated in the detection of complex triazine compounds. HPLC methods have been described for the characterization of the analytes with detection limits of the order of mg dm −3 , but no preconcentration method was available till the introduction of porous graphitic carbon (PGC) in the 1990s [9,10].…”

Flow-injection chemiluminescence determination of chlorinated isocyanuric acids

“…The concentration range of the total cyanurate as stabilizer in pool water is 20-50 mg l -1 . According to the regulations for use of the stabilizer, the free residual chlorine should exceed 2 mg L -1 in order to maintain sufficient bactericidal power [6]. The results ( Table 2) show that the method is suitable for the analysis of water samples.…”

“…It is, therefore, recommended that stabilization of the chlorine content of aqueous solutions can be achieved either by adding isocyanuric acid to solution with the chlorine (as hypochlorite or chlorine solution) or by introduction of chlorinated isocyanurate, directly as a single chemical. The proposed mechanism of stabilization of the residual chlorine by Struys and et al [6] is: Chlorinated Isocyanurates+H 2 O Isocyanuric Acid+HOCl Chlorinated isocyanurates are employed as a disinfectant in swimming pools, spas, household bleaches, automatic dishwasher compounds and hard surface cleaners [1,7,8]. On the other hand, trichloroisocyanuric acid (TCCA) used as source of the strong oxidant Cl + ("positive chlorine"), finds a variety of applications in chemical synthesis [9,10].…”

Flow Injection Chemiluminescence Determination of Sulfide by Oxidation With Chlorinated Isocyanurates

“…So, it is recommended that the stabilization of chlorine content in aqueous solutions, can be achieved either by adding isocyanuric acid to solution with the chlorine (as hypochlorite or chlorine solution) or by introduction of chlorinated isocyanurate, directly as a single chemical. Struys and Wolfs [32] proposed a mechanism of stabilization of the hypochlorite generated in aqueous solutions. Based on this mechanism, existence of isocyanuric acid in the aqueous equilibrium of hypochlorite caused stabilization of hypochlorite even in the presence of sunlight.…”
