An Experimental Study On Hydrometallurgical Process For The Separation Of Lead In Waste Crts Funnel Glass

Waste CRTs display funnel glass contains a lot of lead, and improper disposalof waste CRTs funnel glass is easy to cause greater environmental risks. Three extraction systems of citric acid/sodium citrate, EDTA-2Na, and citric acid/sodium citrate/EDTA-2Na were used to leach the lead in waste CRTsfunnel glass. The effect of extraction rate for three extraction systems was investigated. The results showed that the effect of the extraction systems of citric acid/sodium citrate/EDTA-2Na to leaching the lead in waste CRTs could reach more than 80%, which provides a way for the green treatment of waste CRTs.
