Evaluation of Acetylcholinesterase Biosensor Based on Carbon Nanotube Paste in the Determination of Chlorphenvinphos

Table 3

Determination of chlorphenvinphos in insecticide sample using CNTs-AChE biosensor and spectrophotometric method.

Chlorphenvinphos/mg L^−1
CNTs-AChE biosensor	Spectrophotometric method	𝐸^𝑎/%
225	220	2.27

𝐸^𝑎: CNTs-AChE biosensor versus spectrophotometric method (CNTs-AChE biosensor—spectrophotometric method/spectrophotometric method) × 100%.
