摘要:

The indirect procedure for sulfate determination by Ba absorption spectroscopy was modified so that low concentrations of SO4in small volumes of solutions could be determined rapidly and precisely. Major modifications consisted of seeding the sample with BaSO4, precipitating in ethanol solutions to lower BaSO4solubility, and determining Ba in a N2O‐acetylene flame using the absorption mode.
