Abstract: |
Zn,Li,Sr and metasilicic acid are the four mineral elements in limit indicators of mineral water,which were separately determined in national standard method by some fussy operations.We determined the four mineral elements by ICP-OES.Detection limits for 4 elements are 0.01~0.10 mg/L,we determined 2 kinds of mineral water sold on the market,the standard recovery rates are 83%~100%, relative standard deviation are 0.31%~1.96%,the method is simple and time-saving,has high precision and accuracy,which can be used as a method of discrimination for the mineral water. |
