FIELD: chemistry.
SUBSTANCE: method involves extracting scandium from aqueous solutions with a reagent from the pyrazolone group, separating and dissolving the extract in distilled water, followed by titration. Extracting is carried out in the absence of volatile and toxic organic solvents, antipyrine is used as a reagent, sulfosalicylic acid is used as acid adding a salting-out agent into the system - sodium sulfate at pH of 2.0. Titration is carried out using an indicator - xylenol orange and automatic titrator Mettler Toledo T70.
EFFECT: achieving the completeness of extraction, safety of working conditions, cheapening and a significant simplification of the analysis process.
