Study on Rapid Analysis Method of Trace Chlorine in Methane Chloride
To quickly detect the content of chlorine element in the reaction solution of methane chloride production process,potassium iodide is used as a chromogenic agent to reduce chlorine element in the reaction solution to chloride ions,and iodine ions are oxidized to iodine element,which is determined by visual colorimetry.By establishing a standard color scale,it investigates the effects of reagent dosage,color development time,and other factors on the results.The results show that the method has high accuracy,with a spiked recovery rate of 96.8%to 103.3%,a detection limit of 1 mg/L,simple operation,and can meet urgent production needs.
