The effect of acetic acid extraction time on the dissolution of lead and cadmium in ceramic tiles

Abstract

With the improvement of people's living standard, the glazed tiles will be decorated with some colored glaze materials in order to increase strength and surface decoration effect, and these ceramic tiles containing lead and cadmium will be dissolved out under the action of acid. The dissolved lead and cadmium and other heavy metals after inhalation will affect the human liver, nervous system, hematopoiesis, and even paralysis. The Influence of detection mechanism and detection time on the results is discussed in this paper.
