Method for removing coumafos from beeswax

摘要

A method is for removing coumafos (O,O'-diethyl-O''-(3-chloro-4-methyl-7-coumarinyl)thiophosphate) from beeswax by melting the beeswax, adding activated charcoal to the melted beeswax to form a suspension of the activated charcoal in the melted beeswax, and adsorbing coumafos from the melted beeswax onto the activated charcoal, and then pressure filtering.
