A series of Zn Al hydrotalcite like compounds (HTlc) was synthesized by co precipitation method. The structure and chemical composition of the samples were determined by X ray powder diffraction and automatic X ray fluorescent spectrometric analysis, respectively. The results showed that pure HTlc could be obtained in the range of 0 31≤x≤0 52[x=n(Al)/n(Zn+Al)]. The point of zero net charge (PZNC) and isoelectric point (IEP) of pure Zn Al HTlc were measured using potentiometric titration method and electrophoretic method, respectively. The results indicated that permanent charge led to shifts in the PZNC and IEP of HTlc samples, and this influence was just the same as that of the cations adsorption on HTlc samples. PZNC and IEP all decreased with x or permanent charge density increasing, and IEP values were higher than PZNC values for all samples. The difference value (IEP PZNC) increased as x value increased, indicating that the difference came from the structure charge of HTlc samples.
