Did You Know, Resin Technology Helps to Remove Metal from Cannabis?

Cannabis plants are great at accumulating metal contaminants from soil and are sometimes used for soil remediation as a way to remove these metals from the environment. This property of cannabis is undesirable when using the plant for recreational or medical purposes, as significant levels of toxic cadmium, lead, mercury and copper can be present.

After extraction, these metals can carry over into crude oil, an ingredient in edible cannabis products. Also, the extraction process may be a concentrating aid to bring these to levels surpassing those recommended by the FDA.

Purolite's strong acid cation exchange resins or chelating resins can remove these metals to safe levels to save out of spec product from being wasted. Simple flow through filtration with the media doesn't require advanced equipment or any heat input to the crude oil, and food-grade resin products are available.
