| Abstract: | Acetylcholinesterase was extracted from chicken brain, and the organophosphorus pesticide residues were determinated by enzyme inhibition spectrophotometry. The method presented in this paper has been applied in the determination of parathion, phoxim, omethoate with satisfactory results. Recovery of parathion, phoxim, omethoate were found to be 97%, 101%, 99%, respectively. |
