用硫磺作固定剂千次法处理蜡油.钒用8—羟基喹啉—氯仿萃取富集来提高灵敏度.铜、镍用8-羟基喹啉一丁二酮肟—氯仿萃取分离来消除干抗.本方法的标准偏差为3.22%~11.5%,回收率为91.0%~105.0%.
Sulfur is used as a fixative to treat wax oil in a thousandths. Vanadium is enriched by 8-hydroxyquinoline-chloroform extraction to enhance sensitivity. Copper and nickel are eliminated by 8-hydroxyquinoline-dimethylglyoxime-chloroform extraction The standard deviation of this method is 3.22% ~ 11.5%, the recovery rate is 91.0% ~ 105.0%.
