Hi, I want to degrade metolachlor with ozone under controlled conditions, but i cannot manage how to calculate the theoric amounts of ozone needed. According to published work, degradation is second order, with k metolachlor(O3) = [0,54 - 1,1] L/(mol.s) and k metolachlor(OH°) = [5,1 - 7,1] .10^9 L/(mol.s) I wish to work at pH = 7.2 ; 25°C ; 1 L of pure water and 10 µg/L of metolachlor initially (so 10 µg). Time can be comprised between 10 and 60 minutes. Can someone share knowledge about that? In advance, thank you
The catalytic ozonation of the herbicide metolachlor ( MTLC ) aqueous solutions has been investigated using carbon nanomaterials as catalysts. Multiwalled carbon nanotubes were tested in semi - batch experiments and carbon fibers grown on a honeycomb cordiete monolith were tested in continuous experiments. The application of the carbon catalysts was shown to improve the mineralization degree of MTLC and to decrease the toxicity of the solution subject to ozonation. Degradation by - products were also followed in order to compare the two processes. The use of pesticide in modern agriculture, including herbicides, is considered essential to avoid loss cultures by infestation, which would render the large scale exploration impracticable.

if you have graphical relationship between this parameters you can use Origin software to draw the relationship, and then you can do analysis for this relation by this software.
