Summary of the points of zero charge (PZC) and isoelectric points (IEP) of various materials published in the recent literature and of older results overlooked in the previous compilations. The roles of experimental conditions, especially of the temperature, of the nature and concentration of supporting electrolyte, and of the type of apparatus are emphasized. The newest results are compared with the zero points reported in previous reviews. Most recent studies were carried out with materials whose pH dependent surface charging is already well-documented, and the newest results are consistent with the older literature. Isoelectric points of Gd(OH)₃, Sm(OH)₃, and TeO₂ have been reported for the first time in the recent literature.

近期文献中发表的各种材料的零电荷点 (PZC) 和等电点 (IEP) 的摘要，以及之前汇编中忽略的旧结果的摘要。强调了实验条件的作用，尤其是温度、支持电解质的性质和浓度以及设备类型的作用。将最新结果与之前评论中报告的零分进行比较。大多数最近的研究是用材料进行的，这些材料的 pH 依赖性表面电荷已经得到充分证明，最新结果与旧文献一致。Gd(OH) ₃、Sm(OH) ₃和TeO _{2 的}等电点在最近的文献中首次报道。
