| Abstract: | The turbidimetry of BaSO4 was used to
determine the trace Ba in the mineral water for drinking, the results showed that: The best
amount of 1 10 H2SO4 was 5mL; The correlation coefficient of standard curve could get
the best significant; The recovery was 95-107%; The CV% was 648%; The best time for
turbidity was within 30min after stopping stirring |
