Figure 4From: Preparation of ractopamine-tetraphenylborate complexed nanoparticles used as sensors to rapidly determine ractopamine residues in porkCyclic voltammogram curves. CVs of the bare CPEs (a), the general CPEs (b), and the RT NP-modified CPEs (c) in 0.1 mol/L HAc-NaAc buffer containing 1.0 × 10−3 mol/L RAC. Scan rate of 100 mV•s−1.Back to article page
