Douze cuvettes ont \u00e9t\u00e9 remplies de solutions de dichromate de potassium \u00e0 des concentrations de 20 mg\/L, 120 mg\/L et 600 mg\/L, et quatre cuvettes ont \u00e9t\u00e9 remplies d’une solution d’\u00e9osine Y \u00e0 une concentration de 10^-4 M. Ces cuvettes ont ensuite \u00e9t\u00e9 reconditionn\u00e9es selon notre proc\u00e9d\u00e9.<\/p>\n

Chaque solution a \u00e9t\u00e9 test\u00e9e en double en utilisant des cuves neuves et reconditionn\u00e9es. Les mesures d’absorbance ont \u00e9t\u00e9 effectu\u00e9es \u00e0 257 nm, 313 nm, 350 nm, 430 nm et 517 nm, en fonction de la solution contenue dans les cuvettes.

En outre, l’absorbance a \u00e9t\u00e9 mesur\u00e9e dans des cuvettes reconditionn\u00e9es remplies d’eau pour s’assurer que ces mesures \u00e9taient similaires \u00e0 celles des cuvettes neuves remplies d’eau (voir figure ci-bas).<\/p>\n
