| Abstract: | The paper describes that HG-AAS is used to determine the arsinic in the sludges from oil refining. In the paper are also studied the best conditions in which the equipments work, the samples are treated and experimented, end disturbance of co-existent inon. The results show that the coefficien of variation is 3.86%, the sensitivity is 0.7ng/mL/1%A; and the recovery is 95%～105%. The liner range is 0.0 ～10.0ng/mL. |
