Abstract

Drinking water from the wells in rural households is not always monitored in terms of quality, so a fast and efficient method of analysis it is necessary.
A method for rapid separation and quantitative determination of inorganic ions present in drinking water (well water) was developed.
The experimental parameters were optimized to improve resolution and limits of detection and quantification for the separation of 11 inorganic  cations and anions (Na +, K +, Ca2 +, Li +, Mg2 +, NH4 +, Cl-, Br-, I-, NO3-, NO2-). Thus, we have evaluated the nature and concentration of electrolyte, pH and possible  addition of organic modifiers specific complexing agents. For the  direct and sensitive detection of the analytes capacitively-coupled contactless conductivity detection (C4D)  was used.
The C4D detection parameters were optimized using an experimental design aiming for obtaining the optimum operational parameters (frequency and amplitude)..
Water samples from the rural county of Cluj were collected and analyzed to determine their physical and chemical quality parameters. The results were processed by multivariate analysis (PCA) in order to identify correlations between quality parameters of the well water samples, with the ultimate goal of any sources of pollution monitoring.
