| Abstract | ||||
| A simple, fast and sensitive ion chromatography (IC) method, for the determination of common inos (anion and cation) in water samples was developed. For comparison, selected samples of tap water, underground water, bottled mineral water and filtered tap water were collected and determined from Talkha and some villages, Dakahlia, Egypt. Ten ions of each anion and cation (fluoride, chloride, bromide, nitrate, sulphate, sodium, ammonium, magnesium, potassium, and calcium) were separated and analyzed, respectively. An isocratic elution with 4.5mmol/L Na2CO3, 1.0 mmol/L NaHCO3 and 42 mmol/L methanesulfonic acid (MSA), IonPac AS22 and CS16 as the separation column and DS6 heated conductivity detector was used. The validation of the analytical method was studied in terms of linearity, sensitivity and accuracy. The linearity was between 0.9922 and 0.9992. And the detection limits ranged from 0.4µg/L to 72µg/L (S/N = 3) and satisfactory repeatability (RSD < 2.82%, n = 6).The recoveries were between 91.3% and 116.6%. All water samples were within the safety and acceptable levels of the World Health Organization (WHO, 2006) guidelines. Out of the samples of drinking water, only underground water had the slightly higher levels. | ||||
