Determination of Cobalt in Surface Water and Wastewater by FAAS

This article explored the cobalt determination method from surface water and wastewater through a series of tests in terms of sample pre-treatment,instruments condition optimization,and detection limit,RSD,accuracy and recovery rate.In our test,the detection limit is 0.01 mg/L,the RSD is 0.6%~16%,the accurancy rate is-0.3%(1.01±0.05 μg/mL) and the recovery rate is 90%~104%,the method satisfies the demands from environmental monitoring technology standard,the environment management and environmental assessment system.We suggest that it will make this a corresponding standard by Government.
