The Se(VI) component should be HSeO4 because H2SeO4 does not exist in solution. Therefore, the correct form of Eq. [5] is: 

The changes in equation definition also change the regression equations in the lower right-hand corner of Table 4. The correct regression equations, r2, and P are:

Choosing the regression equation that gives the highest r2 value changes Fig. 4d to:
