| Abstract: | SO3 2? can be determined photometrically with trinitrobenzoic acid within 2 min. SO4 2?, S2O3 2?, S2? and SxO6 2? in concentrations up to 1 mMole/100 ml do not interfere. The limit of determination is 0.22 mg SO3 2?/100 ml, the standard deviation for the determination of 7 mg SO3 2? is ± 0.59 Rel.-%. |
