Flow-Injection Determination of Elemental Iodine by Polyvinyl Alcohol

摘要: Complex formation between elemental iodine and polyvinyl alcohol was studied under flow conditions. The of substances with a weak hyperchromic effect in the UV visible regions detected. It shown that this reaction could be used conditions provided gel-forming ability viscosity solution were reduced by adding isopropanol 6% dimethylsulfoxide. found efficiency monitored using new method for determination dispersion coefficient sample based on comparison standard “flow” absorptivity coefficients. Because nonequilibrium factors, it turns out best calibration function is nonlinear one. throughput capacity 140 samples per hour, limit detection 60 ng/mL. high selectivity chlorides allows one to determine its species seawater monitor concentration white salt.
