Determination of Iodine in Laser Experiment
摘要
Abstract
An analytical method for determining iodine in laser experimentwas developed using ion chromatography and alkalescence active carbon.Iodine inworkplace from laser experiment process was collected for 15 min with flowing 0.5 L/min.Iodine ion of active carbon was desorpted with Na2CO3-NaHCO3 system.The separation of the iodine was achieved on Metrohm A Supp 5 (150mm) anion exchange column with 3.6 mmol/L NaCO3 ~ 1.0 mmol/L NaHCO3 as eluent.The method of relative standard deviation was 0.40% ~0.89%.The correlation coefficient is beyond 0.999 6,The injection volume was 100μL,the detection limit of Iodide was 0.004 mg/L.The method was rapid,accuracy and security.The recoveries of iodine in workplace from laser experiment process was 96.0% ~ 102.5%.The method was easy to operate,it avoided various processes like derivation,and extraction.Optimized the iodine sampling method to the greatest extent in the laser experiment,which made the experiment simple and easy,and the result is accurate and dependable.关键词
