Choon Liang Tan 02.04.08 CHM431 Lab Report 2 Capillary Electrophoresis Determination Of Chlorine, Nitrite, Nitrate, and Sulfate Ions Name: Choon Liang Tan Bronco ID: 007156760 Date: 02.04.08 Abstract: This high-voltage method using capillary electrophoresis was used to try to detect certain compounds within an unknown sample that was given. Each ionic solution of chlorine, nitrate, nitrite, and sulfate was analyzed on its own at 100ppm each. They were analyzed in a mixture whereby chlorine, nitrate, nitrite and sulfate were at 10ppm, 20ppm, 30ppm and 40ppm respectively. After this, the unknown sample was measure and results are that there are nitrite, nitrate and sulfate ions present at 140.83ppm , 60.53ppm and 71.38ppm respectively. This results is however very doubtful because I was specifically instructed by the lab lecturer, that even though I had created the100ppm of chlorine, nitrite, nitrate and sulfate ionic solutions 3 weeks ago on the 15
