Effect of scan rate (25–300 mVs⁻¹) on the cyclic voltammograms of (a) GCE/PANI/ZnO and (b) GCE/PANI/Fe₃O₄ in 500 μM lindane in 60 : 40 methanol/water containing 0.05 M TBAB. (c) and (d) are the plots of current () against square root of scan rate (mVs⁻¹) for GCE/PANI/ZnO and GCE/PANI/Fe₃O₄, respectively.
