Investigation of ionic composition of locally produced bottled mineral water and drinking water / Yasmin Mohd Yusoff
Six different brands of locally produced bottled mineral water and drinking water were analyzed using IC in order to determine the ionic composition in each of bottled water. Cation (Na +, K +, NH4 +, Mg 2 +, Ca 2+) and anion (F ⎯, Cl ⎯, SO4 2⎯, NO3⎯, PO4 3⎯) were analyzed in each of the bottled wat...

| 总结: | Six different brands of locally produced bottled mineral water and drinking water were analyzed using IC in order to determine the ionic composition in each of bottled water. Cation (Na +, K +, NH4 +, Mg 2 +, Ca 2+) and anion (F ⎯, Cl ⎯, SO4 2⎯, NO3⎯, PO4 3⎯) were analyzed in each of the bottled water. Sample taken from each of bottled water and were analyzed three times each. More cations and anions were found in bottled mineral water compared to bottled drinking water whereby the results obtained show average concentration of ionic species in bottled mineral water and drinking water followed the order: Ca 2+ > Na + > K + > Mg 2+ > SO4 2⎯ > Cl ⎯ > F ⎯ > NO3⎯ > NH4 + > PO4 3⎯. Bottled mineral water has higher average concentration of cations and anions compared to bottled drinking water. The highest average concentration of cations species is Ca2+, 28.785mg/L and for anion species is SO4 2-, 5.317mg/L, both are found in bottled mineral water. Most of average concentrations of cations and anions species found in bottled mineral water and drinking water is within the Food Act and Regulations and as well as National Standard for Drinking Water Quality. |
