Table 1. Physico-chemical parameters of waters.
Electric and chemical parameters of deionized water (H2Od), tap water (Watertap) and plasma-activated deionized water (PAWH2Od) and tap water (PAWtap). The conductivity is expressed in relative value differences: Δσ/σ. The measurements of concentrations, pH and conductivity are made 3 times independently.
| Water | H2O2 concentration (mg.L-1) | NO3- concentration (mg.L-1) | Variation of electrical conductivity Δσ/σ | pH |
|---|---|---|---|---|
| H2Od | 0 | 0 | Δσ H2O2d | 7.41 ± 0.13 |
| PAWH2Od | 17.0 ± 0.1 | 0 | 20 x σ H2O2d | 7.07 ± 0.04 |
| Watertap | 0 | 5 ± 2 | σ Watertap | 8.02 ± 0.25 |
| PAWtap | 25.5 ± 0.1 | 15 ± 2 | 2 x σ Watertap | 7.62 ± 0.13 |
