化工材料pH值例行分析及应用

PH Analysis of Chemical Materials and Application in Practice

pH值是指原材料水溶液的pH值,所以pH值测定都依赖于水,测定过程总是将材料转变为水溶液、水萃取液或水分散体,然后进行测定。由此可见,必须首先进行水的pH值研究,然后才能谈及材料的pH值问题。对pH值的测定方法依材料的性质不同而不同,很有必要研究一套较通用的测定方法。从研究水的pH值开始,其后在对各种非金属材料的pH值例行分析进行初探。

The pH is water solution pH of material, So chemical materials all need to be changed to water solution,extract/on of water or water dispersoid in determination. Be showed from this, we must to study pH of water and then can speak about the pH of the materials problem. The way is dissimilarity for pH determination and to study a universal means. Depend on the property of the material dissimilarity but dissimilarity to the measurement method of the pH, have a necessity to study a set of general measurement method. One of the main contents of this thesis is the pH of the water the beginning is from the research, afterward be being worth routine analysis to carry on a preliminary study to various pH of nonmetal material.
