Surface study of vitreous carbon obtained from glassy carbon powder
This work presents a surface study of monolithic vitreous (or glassy) carbon - MVC - obtained from vitreous carbon powder. Defective MVC pieces are crushed in a ball mill and size classified by sifting. The MVC powder is ...
Screen-printed carbon electrode modified with poly-L-histidine applied to voltammetric determination of chromium (VI)
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 ...
