摘　　要：四氯化碳作为萃取剂在红外法测定水中油时被广泛使用。为保护环境和资源再利用 ,对精馏法和活性炭两种回收废四氯化碳的方法作了研究。两种方法各有特点 ,适用于回收不同的废液。对回收合格的四氯化碳进行的质控试验表明 ,两种方法均能得到满意结果 。Carbon tetrachloride (CCl 4) is widely used as extractant in the determination of oil in water by IR method. In consideration of environmental protection and resource reutilization, two methods for recycling used CCl 4, rectification method and activated carbon method, were studied. Each method has its own characteristics and is fit to recycle certain kinds of waste. The quality control tests of recycled CCl 4 show that both methods obtained satisfactory results and both are feasible.
