Extracting multiresidual pesticides


Pesticide grade Florisil is a selective adsorbent comprised of synthetic magnesium-silica gel activated at 675 ˚C. It’s strongly polar, extremely active, highly porous and able to retain low to moderate polar compounds such as chlorine-, nitrogen- and phosphorus-containing pesticides.

In analysis of multiresidual pesticides, Florisil has proven to be an effective, low-cost choice, and adopted in the U.S. EPA method 608 and China NY/T method 761.
