Abstract Solution Cathode Glow Discharge-Atomic Emission Spectrometry is a novel, rapid, high efficient and real-time online element analysis method, which can be applied for metal elements detection in water. In this paper, the internal standard method was employed to improve its accuracy and stability. The standard calibration curve of potassium and the internal standard calibration curve of potassium were established using Hβ as internal standard elements, and the relative error and relative standard deviation of the sample measured by internal standard method were 1.11% and 2.14%, respectively. Compared with the standard curve method, the accuracy and stability were improved by internal standard method. Variations of spectral line intensity at the same periods were investigated, showing the spectral line intensity variations of potassium and Hβ were not quite the same, but the spectral line intensity variations of potassium and rubidium, calcium and magnesium in the same main group had the same variable trends, thus, we proposed that the elements which had the same variable trends of spectral line intensity and main group with the determined metal elements could be selected as the internal standard element to have a greater correction for metal elements detection in water using solution cathode glow discharge-atomic emission spectrometry. The accuracies and stabilities of internal standard method when rubidium, magnesium and calcium were used as internal standard elements for potassium, calcium and magnesium were discussed and the relative errors were 0.49%, 0.02% and 0.30% respectively, and the relative standard deviations were 1.11%, 1.13% and 0.87%, respectively, which is better than the standard curve method and the internal standard method using Hβ as the internal standard element. The relative error and relative standard deviation of the calcium and magnesium in tap water were also measured, which showed that the relative error and relative standard deviation were 0.58%, 1.03% and 1.57%, 1.10%, respectively, when magnesium and calcium were used as the internal standard spectral elements respectively. The results show that the internal standard method is a useful method to eliminate the influence of experimental fluctuations, which improves the accuracy and stability when solution cathode glow discharge-atomic emission spectrometry is applied for metal elements detection in water.
