Surfaces are often characterized by their points of zero charge (PZC) and isoelectric points (IEP). Different authors use these terms for different quantities, which may be equal to the actual PZC under certain conditions. Several popular methods lead to results which are inappropriately termed PZC. This present review is limited to zero-points obtained in the presence of inert electrolytes (halides, nitrates, and perchlorates of the 1st group metals). IEP are reported for all kinds of materials. PZC of metal oxides obtained as common intersection points of potentiometric curves for 3 or more ionic strengths (or by means of equivalent methods) are also reported, while the apparent PZC obtained by mass titration, pH-drift method, etc. are deliberately neglected. The results published in the recent publications and older results overlooked in the previous compilations by the same author are reported. The PZC/IEP are accompanied by information on the temperature and on the nature and concentration of supporting electrolyte (if available). The references to previous reviews by the same author allow to compare the newest results with the PZC/IEP of similar materials from the older literature.
表面通常由其零电荷点（PZC）和等电点（IEP）来表征。不同的作者对这些术语用于不同的量，在某些条件下这些量可能等于实际的PZC。几种常用方法得出的结果被不恰当地称为PZC。本综述仅限于在惰性电解质（第一族金属的卤化物、硝酸盐和高氯酸盐）存在下获得的零点。报告了各种材料的IEP。还报告了通过3种或更多离子强度的电位曲线的公共交点（或通过等效方法）获得的金属氧化物的PZC，而通过质量滴定、pH漂移法等获得的表观PZC则被有意忽略。报告了近期出版物中发表的结果以及同一作者在先前汇编中忽略的较早结果。PZC/IEP伴有关于温度以及支持电解质的性质和浓度（如果可用）的信息。同一作者先前综述的参考文献允许将最新结果与来自较早文献的类似材料的PZC/IEP进行比较。
