| Abstract: | A method for determination of chlorine in reforming catalyst by ion chromatography with eluent autogeneration was established.Chlorine in reforming catalyst was extracted by 4 mL sodium hydroxide solution of 7.5 mol/L,and determined by ion chromatography using potassium hydroxide solution generated by eluent generator as mobile phase.The linear relation of chlorine of solution was good,the correlation coefficient was 0.9999.The relative standard deviation was less than 0.8%,the recoveries were 98.7% to 102.... |
