中文摘要 | the electrochemiluminescence (ecl) of tris(2,29-bipyridyl) ruthenium(ii) [ru(bpy)(3)(2+)] ion-exchanged in the sulfonic-functionalized mcm-41 silicas was developed with tripropylamine (tpra) as a co-reactant in a carbon paste electrode (cpe) using a room temperature ionic liquid (il) as a binder. the sulfonic-functionalized silicas mcm-41 were used for preparing an ecl sensor by the electrostatic interactions between ru( bpy)(3)(2+) cations and sulfonic acid groups. we used the il as a binder to construct the cpe (il-cpe) to replace the traditional binder of the cpe (t-cpe)-silicone oil. the results indicated that the mcm-41-modified il-cpe had more open structures to allow faster diffusion of ru( bpy)(3)(2+) and that the ionic liquid also acted as a conducting bridge to connect tpra with ru( bpy)(3)(2+) sites immobilized in the electrode, resulting in a higher ecl intensity compared with the mcm-41-modified t-cpe. herein, the detection limit for tpra of the mcm-41-modified il-cpe was 7.2 nm, which was two orders of magnitude lower than that observed at the t-cpe. when this new sensor was used in flow injection analysis (fia), the mcm-41-modified il-cpe ecl sensor also showed good reproducibility. furthermore, the sensor could also be renewed easily by mechanical polishing whenever needed. |
