Abstract
The presence of silver ions deforms strongly the linear response for sodium determination by name spectrophotometry. Relative errors up to 60 % can be obtained if linear instead of non-linear relations are used. A correction function is defined and a method based on mathematical considerations is pr oposed for elimination of interference in determination of sodium concentra tion.
