介质的酸效应、沉淀效应如何影响陶瓷铅溶出量的测定

HOW THE ACID EFFECT AND PRECIPITATION EFFECT OF THE MEDIUM INFLUENCE THE MEASUREMENT OF THE LEAD RELEASE OF DAILY-USE CERAMICS

分析了含有不同介质的4％(V／V)乙酸浸提液中,介质的酸效应、沉淀效应对日用陶瓷铅溶出量测定的影响,指出沉淀效应是影响陶瓷铅溶出量的主要因素。

This article is to analyse how the acid effect and precipitation effect of the medium influence the measurement of the lead release of daily-use ceramics in 4PCT （V/V） leach liquor of formic acid which contains different media. It points out that precipitation effect is the main factor.
