Abstract
A method for extraction-spectrophotometric determination of natrium dodecylsulphate includes formation of ion associate of natrium dodecylsulphate with organic base, its extraction with organic solvent and following photometering of extractions. As organic base one uses basic dye astraphloxin FF, as organic solvent – mix of tetrachlormethane with dichlorethane at ratio 4:1, and transition to ion associate is carried out at concentration of dye 0,0001 mol/l and acidity of medium pH 1-8.
