电子废弃物显像管玻璃中Pb渗出的研究

Exudation of Pb in Glass Tube

文章对显像管玻璃中Pb渗出机理分析并通过实验证明,用水、盐、酸和碱溶液处理显像管玻璃后,都会有铅渗出。因此如果将显像管玻璃随意丢弃,会有大量的铅渗出并进入环境,对环境产生极大危害。所以必须加大宣传力度,使人们都认识到丢弃显像管的危害性。并尽快的回收、处理废旧显像管。

With the development of information industries, electric waste pollution is becoming more and more serious. The glass tubes in discarded computers and TVs contain much lead which is no less than that contained in lead-acid accumulator, however there is little study on exudation of Pb in cone-glass. Restilts showed that if glass tubes were discarded without any treatment, the lead contained would seep out into the environment and did great harm to environmental conditions. As a result it is ui＇gent to recycle and reuse waste tubes.
