Abstract
|
|
|
|
The analytical in vivo chromium ion was searched for using a voltammetric hollow-fiber dialysis sensor via square wave stripping voltammetry (SW), cyclic voltammetry (CV), and chronoamperometry. Under optimum parameters, the analytical results indicated linear working ranges of 50~400 ㎎/l CV and 10~80 ㎍/l SW within a 30-sec accumulation time. The analytical detection limit (S/N) was 6.0 ㎍/l. The developed method can be applied to in vivo tissues and in ex vivo toxicity assay, as well as to other materials that require chromium analysis.
