The adsorptive voltammetric behavior of the aluminum (Al)-alizarin violet (AV) complexin 0.2 molL-1 HAc-NaAc buffer (pH 4.5) at a multi-walled carbon nanotube modified carbon paste electrode (MWCNT/CPE) was investigated. The results showed that the complex can be adsorbed on the surface of the MWCNT/CPE, yielding one oxidation peak at 530mV (vs. SCE). The proposed method exhibits good linearity over the range from 1.0x10-9 mol L-1 to 1.0x10-7 mol L-1, and a low detection limit of 6.0x10-10 molL-1 for 120 s accumulation was obtained u...
