A critical review of the points of zero charge (PZC) obtained by potentiometric titration and of isoelectric points (IEP) obtained by electrokinetic measurements. The results from the recent literature are presented with experimental details (temperature, method, type of apparatus, etc.), and they are compared with the zero points of similar materials reported in older publications. Most studies of PZC and IEP reported in the recent papers were carried out for metal oxides and hydroxides, especially alumina, iron oxides, and titania, and the results are consistent with the PZC and IEP of similar materials reported in older literature, and summarized in previous reviews by the same author. Relatively few studies were carried out with less common materials, and IEP of (nominally) VO2 and BN have been reported for the 1st time.

pH依赖的表面电荷和零电荷点。八。更新。

对通过电位滴定法获得的零电荷点（PZC）和通过电动测量获得的等电点（IEP）进行了严格的评述。最新文献的结果带有实验细节（温度，方法，设备类型等），并与较早出版物中报道的相似材料的零点进行了比较。最近论文中报道的大多数PZC和IEP研究都是针对金属氧化物和氢氧化物，尤其是氧化铝，氧化铁和二氧化钛进行的，结果与较早文献中报道的类似材料的PZC和IEP一致，并总结于同一位作者以前的评论。相对较少的研究是用不太常见的材料进行的，并且首次报道了（名义上）VO2和BN的IEP。
