中文摘要：

危险电子废物阴极射线管（cathode ray tube，CRT）是当前我国电子垃圾处理处置中首要必须解决的难题，其关键在于含铅锥玻璃的处理处置。本研究探讨了真空碳热还原法从CRT锥玻璃中分离并回收有害重金属铅的同时回收钾和钠的规律。结果表明，铅、钾和钠的回收率随温度的升高、压力的降低、碳加入量的增加及保持时间的延长而增大；当温度为1000℃、系统压力为10Pa时，加入10％的碳粉并保持4h，铅回收率接近100％，钠和钾的回收率分别为65．04％和50．55％。该方法为废弃阴极射线管玻璃的无害化和资源化提供了理论依据和实验数据。

英文摘要：

Cathode ray tubes （CRT） , the hazardous electronic waste, is addressed as the first and foremost problem that must be solved in current China＇ s electronic waste disposal, and the key of which lies in the detoxification and reutilization of lead-contained funnel glass. In the present study, Pb was successfully removed and recovered from CRT funnel glass by vacuum-aided carbothermal reduction, while Na and K were also simultaneously recovered. Experimental results showed that metal recovery rates increased with the increase of temperature, carbon adding amount, holding time and the decrease of pressure. The optimum temperature, pressure, holding time and carbon adding amount were 1 000℃ , 10 Pa, 10% and 4 h, respectively. Metal recovery rates under the optimum conditions were close to 100% for Pb, 65.04% for K and 50.55% for Na, respectively. This study could establish theoretical basis and provide valuable data for detoxifieation and reutilization CRT glass
