摘要：

Square-wave voltammetry (SWV) is applied to the quantitative analysis analysis of berberine in supporting electrolytes of different pHs. In 0. 1 mol/dm**3 aqueous solution of NaCl plus HCl (pH 2) the lowest detectable concentration of berberine is 0. 006 mu g/ml. The sensitivity of SWV can be increased by prolonged adsorptive accumulation of berberine. The adsorption of berberine is a complex process which includes phase transformation, especially in neutral and basic media.
