that several molecular emission lines at 283.0 and 308.9 nm ascribed to OH bands (A2 Σ+ → X2Π) are found [24]. It was reported that the OH band shown in this spectrum is attributed to a recombination process of the precursor species of OH+ [25]. Molecular band spectra of N2 ranged from 315–406 nm and assigned to the C3 Πu → B3 Πg systems are observed in LCGD because ambient air is used as the discharge gas [26]. In addition, the atomic lines of hydrogen Balmer (α and β) are at 656.3 and 486.1 nm. All these lines are consistent even if no metal ions are dissolved in the solution. The emission lines of K, Na, Ca, Mg and Zn in waste water samples are recorded at 766.5 or 769.9 nm,
589.0 or 589.6 nm, 422.7 nm, 285.2 nm and 213.8 nm, respectively [10]. The results suggested that it is feasible to use the designed LCGD source to determine metal elements in aqueous solutions.
