Method for measuring chlorotoluron content
Publication date: 2009
The invention discloses a method for measuring chlorotoluron content. Obvious electrochemical signals are present on a platinum electrode surface in potassium ferricyanide solution. When molecule chlorotoluron to be measured reacts with chlorotoluron molecular engram, the electrochemical signals on the K3 [Fe(CN)6] platinum electrode change, thus an electrochemical analysis method for measuring chlorotoluron content is established. The solution to be measured is scanned using cyclic voltammetry and the scanning voltage is -0.2V to 0.6V and the linear relationship between chlorotoluron content in concentration range of 3*10[-7]mol/L-1.5*10[-6]mol/L and peak current value I is good. The method conquers the defects of the prior technique such as very complex and has high sensitivity and good detection effect for chlorotoluron of 10[-7] mol/L.
