Hello,
I am trying to calculate the percent of each vanadium species as a function of the total vanadium concentration for a particular groundwater sample (script is attached). However, when I sum all the V species predicted, the sum of their concentrations is lower than total input V concentration. For the sample attached, the total V concentration is 0.19 nmol/kg, but the sum of the predicted species is 0.17 nmol/kg, or 22 pmol/kg lower. There is probably something obvious I am missing, but I have not encountered this problem before.
Thank you!
Kat
