Screen-printed carbon electrode modified with poly-L-histidine applied to voltammetric determination of chromium (VI)
(2006-12-01)
The present work reports the use of a screen-printed carbon electrode (SPCE) modified by poly-L-histidine film to determine chromium (VI). Stable films can be formed by direct addition of PH solution 1 % (w/v) on the ...
